It's used to blow the 20 amp fuse in the DC output line; I believe it's
just a 35 amp 1/4" stud-mount SCR, and many SCRs rated at 35A or higher
can replace it if they'll fit on the board.
eg: NTE 5542 (35 amp) NTE 5567 (80 amp)
The short terminal is the gate, the long is the cathode, and the stud is
the anode.
NTE does not list a direct replacement, probably because its an obsolete
part, but you can get to an NTE equivalent via other cross-reference sites:
Dale Wentz's page at http://www.d8apro.com/heath3.htm
crosses the NL576A to a SPS135, which NTE does not list, but another
web site with a cross-reference page crosses that to the 2N3896:
http://www.hutsonind.com/crossref.shtml
and NTE crosses that to their NTE 5542. NTE lists their distributors at
http://www.nteinc.com/NET_St_lst/Disty.html
Also, Mouser in Texas http://www.mouser.com
has the 5542 as their part #
526-NTE5542
for $9.63.

Subject: Re: Capacitor needed for HW-16 please
Frank,
I don't think you're gonna find a new can with those specs. You can
probably get a used one, but do you really want a used electrolytic? Your
best bet is to get individual electrolytics from a supply house like
Mouser and eliminate the big can. If you're like most and want to keep
the original "look", you can even hollow out the can and stuff it with
the new caps. Plan ahead and determine whether the radial or axial lead
varieties will work best (maybe using both types). I've done this with a
number of old rigs and it works great.

Don't know if ' mickey mouse ' tried to fix it...or it's a legimate factory

The two resistors across the caps in the power supply should be 10K at 10
watts. On the low voltage side, R29, should be 1K, at 2 watts. The "-B"

Subject: F/S: 10" boat anchor speaker, 4 Ohms
I could not find a suitable speaker for my receiver, so I decided to
build my own. I bought a pair of stereo speakers ( they would not sell me
only one) And built my own enclosure from 3/4" MDF with glued and stapled
joints. There is a 10" low and mid-range speaker coaxially mounted with a
4" mid to high range. They are both 8 Ohms but when connected in parallel
the resulting impedance is 4 Ohms. The housing is 11-3/4" square with
1/4" added by the feet and 7-3/4" deep. Painted grey but repaintable to
match your equipment. Sounds good to me.
Since I had to buy 2 speakers, I made 2 of the above. I only need 1 so
the other is up for sale. I am asking $50 plus shipping. I have more than
that in it but I feel that is all a person would be willing to pay. Pix
available on request. Thank you.

Fred,
I can relate to your description of "glossy to primer flat". It seems that
there is not too much out there available in semi-gloss finishes.
There is another one that I found at one of the automotive supply stores
(Pep Boys I think).
It is Dupli-Color DA1603 Semi-Gloss Black.
This has worked well to restore the bezels on some test equipment that are
niether gloss or flat but are in between.

Greetings. If you've ever tried to match a near flat black color on older
gear, but glossy is too much so and flat is too much like priimer, listen
up. Krylon 1613, Semi-Flat Black is the right stuff. I painted the top of
a cabinet that was discolored from stuff being set on it and it matched the
rest of the unit perfectly. I found it at a Fred Meyer store in Oregon.

Try the "satin" finish. That is about half-way
between gloss and flat. I use satin finish for all of
the computer matched paint that I get for boat anchor
cabinets from Sherwin-Williams. It usually looks
pretty much "right on" to the original finishes.
Most cans of spray paint are available in satin
finish.

You really want acryllic paints if you can find them

From: Mark S Graalman
Subject: Heath receiver performance numbers
Just for the sake of comparison, I've measured the
MDS (minimum discernable signal), TTDR (two-tone
dynamic range), and BDR (Blocking dynamic range)
of a few Heath receivers. Now there are some REAL
numbers to use in comparison to other rigs.
The numbers for the SB-303 and SB-104 were
measured by Sherwood Engineering, the rest where
measured by me here in my shop.
SB-301:
MDS -138 dBm
TTDR (20 Khz spacing) 83 dB
BDR (20 Khz spacing) 118 dB
SB-303:
MDS -135 dBm
TTDR (20 Khz spacing) 66 dB
BDR (100 Khz spacing) 104 dB
SB-104
MDS -123 dBm
TTDR (20 Khz spacing) 79 dB
BDR (100 Khz spacing) 92 dB
HW-101 (JKR/JCJ optimizing mods installed)
MDS -138 dBm
TTDR (20 Khz spacing) 82 dB
BDR (20 Khz spacing) 95 dB
HR-1680
MDS -137
TTDR (20 Khz spacing) 81 dB
BDR (20 Khz spacing) 105 dB
Since the SB301 and 300 are basically the same unit the
numbers should be about the same, the same would go for the
HW-101 and the SB-102.
The biggest departure from typical of the era performance in
these rigs is the lousy ultimate rejection of the I.F. filter which
is about 70 dB. It can also be seen that the SB-303 has way
too much gain, the SB-300/301 is actually a much better unit
in terms of overload resistance.
Keep in mind also that these numbers were taken on rigs that
are working perfectly and have had a good instrument alignment.

Subject: Re: [Heathkit] Heath receiver performance numbers
I have had pretty much the same performance on the
SB-301. However, my service monitor drops out of
"lock" at about -135 dBm! But, the SB-301 is still
"going strong" at that level. I get similar responses
out of my 75S-3A and one of my 75S-1 receivers. The
other 75S-1 drops out about -135 dBm just before the
service monitor drops out of lock! This is with the
internal attenuator. I could plug in an external
attenuator and get a better reading.
The SB-303 that I owned didn't get as good a MDS
reading as what you got. It tended to be a "bit"
noisey even when properly aligned.

Subject: tales of trouble ie the HW5400
well boys and girls...
after spending two weeks on this HW5400 yesterday, I have come to the
conclusion that the HW5400 is the most screwed up radio heathkit ever put
out on the ham market
ah.. but your thinking that perhaps this is just one rotten egg in the
basket.
well this is number three that I have owned. All have the same problems.
1. The thing clicks when the main tuning knob is turned. Although the
receiver is muted to prevent chirping as the PPL lock and unlock as you
tune. The receiver still has a slight click as you tune the knob.
2. Unbelievable ho-hum receiver. Forget about "working the weak one" with
this HW5400. Signals 4 khz away cause the agc to pump.
3. Really goofy and I mean GOOFY power supply connections as well as speaker
connections. What were they thinking of?
4. The matching power supply runs so hot under load I would be afraid it
could catch fire. Fan cooling is a must. (Who says you need a tube rig to
warm the shack!)
5. Although a mute point now, the HW5400 is (was) just way more than joe ham
could handle. Three PLL, two VCOs, microprocessor oh my! The SB-104 is a
walk in the park compared to the HW5400
6. Personal opinion, but the knobs are way too small. Especially the volume
and RIT knobs.
All and all, I'll take the SB-104 any day. In fact, I have 23 SB-104s
sitting in the shack, and only one HW5400.
Perhaps I'll try another one and see if it is a wacked up as the one I have
now. I know the other two I did own, were not better, just as screwed up..
Will be down at dayton this year, same spots as before, 509, 510 and 511.

Front panel almost perfect! Original black cabinet with handle in perfect physical condition but missing a little paint on top.

I would repaint it myself, but I have some physical limitations and the radio is too heavy for me to wrestle with all alone. Includes nice copy of original manual.

Subject: Re: output transformers measurement. Off topic?
How about using a simple voltage divider -
Connect an audio oscillator (say 2v at 1 kHz) across the series combination of
a 10K resistor and the transformer primary. Measure the voltage across the
resistor and across the primary.
Primary_impedance = 10K*primary_volts/resistor_volts.
This assumes you have the proper secondary load - make your best guess about
the 8 ohm winding and put an 8 ohm load there. If you aren't sure, vary the
secondary load connection and observe the results on the primary and make an
average estimate.

Subject: SB-104 display board update
boys and girls...
after some conversations with several guys here on the reflector about the
possibility of using the original heathkit display driver IC on the new LED
display board..
the original driver ICs sink current. in the original version they sink the
current from the +180 volt supply.
in my updated LED version the 7447 sink current from the +5 supply via 180
ohm current limiting resistors
In the "why not give it a try" column I put in the original high voltage
driver and low and behold they work!
The display is not as bright and the limiting resistors would have to be
changed.. did not compute the values ... a good starting point would be 100
or 75 ohms...
now having said that, I will be offering the LED update PC board, displays,
IC sockets and original 180 resistors for $32 +$4 shipping.. Bare PC boards
are still $15+$4 shipping
this offer is only for the guys on this list, nothing will be placed on the
web site.
and there will be no warranty that the old driver ICs will withstand the
current.. it's a experiment.
Will be out of the office this weekend, going to the toledo hamfest..
anyone interested in this project, drop me a email..
parts in stock..

Subject: low voltag power strip aka rigrunner knock off for heathkit radios
boys and girls..
got to many hw-8s, HW-202 and SB-104s?
only one power supply?
well it's been a long winter and I had way too much time on my hands..
so, I designed a rigrunner clone. It uses the amp power poles, fuses, leds
and by pass capacitors.
the whole shebang is connected to your power supply via a heavy duty cable.
That way you don't loose one of your power pole connectors when you hook up
power to the strip.
there will be two flavors..
one is a five outlet affair and lacks any real bells and whistles... it does
have LED fuse failure indicators. Yes, it has fuses..
version two will have 10 outlets and overvoltage, under voltage warning LED
and a few more LEDS such as power, reverse polarity and so on.
Neither version will be offered at this time with a case...
If there is enough interest, I'll have a run of PC boards made for the 5
outlet first and if enough interest will do a run of the 10 outlet pc board
prices?
the board only for the 5 outlet will be $14 +shipping
the board only for the 10 outlet will be $18 + shipping
again, if the interest is there might offer a complete kit including the
power poles..
I work in a steel mill, so having been around big heavy things ( not taking
into account my first wife) for 32 years, the design for the power strip is
industrial strength!
I ran 85 amps through the prototypes without heating the traces!
both boards are rated for 40 amps..
3 oz copper traces over a half inch wide. Double sided PC board with top and
bottom solder masks. Silk screen on the top side.
the original prototype used a "maxi" fuse but I have changed it back to the
atc type because of a problem with wrapping a case around the pcb and having
the top too high to get to the small atc fuses.
drop me an email if interested...
have fun keeping the green flame burning..

From: Neil Morrison
Subject: Re: output transformers measurement. Off topic?
Basically, no, you can't do this. You can estimate the power rating
from the cross section of the core; measure the turns ratio; and
measure the open circuit impedance of the primary but that's it.
A 4K to 4 ohm transformer is also an 8K to 8 ohm transformer.
Neil
>From Scroggie:- "Radio and Electronic Lab Handbook".
11.3. A.F. TRANSFORMERS
The effective frequency band of an a.f. transformer is limited at
the low end by shunt inductance and at the high end by leakage or
series inductance. Shunt inductance, so called because it acts as a
by-pass to the transformer load impedance, is simply the inductance
of the primary. It should be measured at a low frequency, to ensure
that the effect of stray capacitance is negligible; 50 c/s is usually
suitable. Working conditions should be reproduced as nearly as
possible during measurement, as regards amplitude of a.c. and d.c.
(if any). Suitable methods are described in Secs. 9.18 to 9.22.
Leakage inductance is relatively small, and is a measure of the
extent to which the primary is not completely coupled to the
secondary. The equivalent total leakage inductance referred to the
primary is the inductance measured on the primary side when the
secondary is shortcircuited. Although it affects the high frequency
end, there is no reason why it should not he measured at the same low
frequency as the shunt inductance, except perhaps that its reactance
is then rather small.
Self-capacitance is an important parameter of intervalve
transformers, but these are now rarely used; in output transformers
it often plays only a minor part. But it may have to be considered
when the output transformer is in a negative-feedback loop,
especially since it is increased by the means adopted in the better
transformers to reduce leakage inductance—the interleaving of primary
and secondary windings. With this arrangement one may not be safe in
assuming that the stray capacitance is equivalent to a constant
capacitance in shunt with the primary and independent of frequency,
and instead of trying to measure it as such it is better to measure
the phase shift (Sec. 10.7).
The efficiency of an output transformer can be measured by means of
an output meter and a.f. signal source. The source should be adjusted
to give a suitable amount of power, measured first by the output
meter connected directly to it, and then through the transformer. If
the transformer ratio is n : 1 and its optimum load resistance R, the
resistance of the output meter should be as near as possible to n*n*R
for the first reading and R for the second. The efficiency is the
ratio of the second reading to the first, and should be measured at
the lowest, highest, and one or more intermediate frequencies.
Alternatively this power ratio can be expressed in dB (Table 14.17)
and is then called the transformer loss. For this method it is
necessary for the output-meter transformer not only to have the
appropriate pair of ratios but also reasonably equal efficiencies at
these ratios, at all frequencies concerned. If there is any doubt
about this—or if an output power meter is lacking—the measurement can
be made by a valve voltmeter or even c.r.o. across the appropriate
resistances.
An important characteristic is non-linearity, reckoned as the amount
of distortion caused under specified conditions by a specified signal
amplitude, or alternatively the maximum signal power for a specified
amount of distortion. Perhaps the most useful information, covering
both of these, is a curve of distortion against amplitude or power.
Methods are the same as for a.f. amplifiers; see Secs. 11.12 to
11.16.
It is of course most essential that working conditions or their
equivalents are reproduced—the same amount of d.c. and the same
impedances connected to the windings.
Ref: "Harmonic Distortion in A.F. Transformers", by N. Partridge.
(W.E.), Sept. to Nov. 1942.

Subject: Re: output transformers measurement. Off topic?
While on the subject of audio output transformers, maybe someone can help me
out on this one. I need a 36 Henry choke in series with the audio plate
lead of an audio output tube. What output transformer will give me
inductance around this value? Does anyone know? (I'd like to build a
Paraset clone and it calls for a choke this size). The choke can't be too
big physically. Would a 4000 ohm or 7000 ohm output transformer have
inductance near this value (on the primary)? Sure would like to hear from
anyone who knows. That's a lot of inductance and it has to pass the current
to drive a 6SK7 audio amp. The whole transceiver is in a case approx 2 1/2
x 8 x 6 1/2 inches so I can't be using a 200 ma choke.

Subject: Heathkit IM-103 Line Voltage For Sale
Heath Team;
I have an IM-103 Line Voltage Monitor for sale. Works great. I've
repaired it and calibrated it to my Digitial VOM. It has had a mod done
to the sides of the case that are not noticable from the front. Front
and meter are excellent. I can provide pictures. Price is $55.00 US
funds and I'll include a copy of the manual and shipping (Canada and US
lower 48) for that price. Thanks.

Murray -
TOA makes a very nice handheld battery operated impedance meter model
ZM-104. It is exceptionally handy when working with 70 Volt lines.

Subject: Re: d104 schematic
For the D104 schematic try the following ftp site:
ftp://216.24.174.245/astatic/d104tg/ Right click to download.
You will need the DjVu reader from either:
http://bama.sbc.edu/viewers.htm or
http://www.lizardtech.com/download/dl_options.php?page=plugins
The D104 connects to the SB-101 with audio on pin 1, PTT on pin 2 and
shield/PTT return soldered to the shield spring.
