Arthur - those tubes are for the Globe King 400 transmitter!

I once owned one of these beasts and could NOT persuade the V-70D triodes
to stop self-oscillating no matter what I did with them.

I ran out of time and patience and regrettably I sold the radio transmitter.

Now, there are still a few GLOBE KINGS around, and the guys who own them
would probably love to buy those tubes from  you.

I will pass the word around among them and see what happens.

V-70D triode:

PINS 1 and 4 = Filament (Cathode)
Pin 2 = N/C
Pin 3 = GRID
Plate Cap = Anode 

MAXIMUM RATINGS:
Plate Dissipation 85 watts
Plate voltage 1750 V DC
Plate Current 200 mA
DC Grid current 45 mA
Filament 7.5V at 3.25 A
Grid voltage -80 to -100V DC

Power Output is in the range of 120-225 watts per tube depending on the
operating conditions. Plate voltage of 1250 V DC with -72 volts on the grid
will give you 120 Watts out.

I'd recommend turning the wick down a little so that they will last a long
time if you plan to use them!

I will forward our messages to [email-masked] and ask the guys there
to please post it also on the BOATANCHORS group in case someone needs these
and wants to contact you.

I hope that this has been helpful!

Message-ID: <[email-masked]>

Guys I saw this on the packet BBS swap and thought that some of you might be
interested. Contact him not me.

Our local radio club, of which I am the President, recently received a
donation of 4,669 tubes from a local electronics dealer.  These tubes are
all A-1, brand new, sorted out, counted and in excellant condx. There are a
lot of them.  Anyone who would like these tubes for a Donation of $200.00 to
the Holland Amateur Radio Club can have them shipped to your door.
Interested parties can contact me, The HARC president at (616)772-0367.
Thanks.

He didn't give his name or call but from the packet heading I think it's
K3JZ. At less than 5 cents per tube it might be worth a call.  73 Jim K4CGY

Subject: Grandma Hartley Sports a New 805 Tubetopper with Gusto!
Message-ID: <[email-masked]>

After I put the nondescript 450 volt dynamotor on ol Grandma Hartley,
she was just not quite here ol' stable self (as those that heard her
originally can attest).  So, in a fit of fun (as opposed to a towering
rage), I went a'lookie-seein' ta wat was da matter.  Typical of loose-
coupled Hartleys, she were a sweatin' a tad much in the plate current
department.  Upping the Grid Bias resistor from 7K to 20K helped, but
long-term heating drift of up to about 750 cycles was still there, even
with perfect keying and relatively stable power.  It seems the ol' 801A
of 10 years fine service just could not quite handle the higher power
without heating.  In Hartley oscillator service, it is always a good
rule of thumb to never run it greater than about 1/3 to 1/2 the plate
dissipation of the tube, to keep electrode heating to a minimum.
The 801A should be rated at about 7.5-10 watts plate dissipation, and
I was pushing ol' Grandma at 10 watts input or a little more.  So, with
some searching, I found a lusty ol' bottle, a type 805, plate dissipation
at around 75-100 watts.  After doing a socket swap and puttin' on a plate
cap lead down to the plate terminal of the 50watter socket, I can now plug
in a 211 style or an 805 style biggiefirebottle and let ol' Grandma Hartley
rip/snort with the best of them.  When I fired her up, she was her ol' self,
again, with a fine T8.95 note and a lusty 5 watts out and about 10 input.
That HUGE firebottle emits enuf glow to light up the operating table, and
is bigger than ol' Grandma herself.  A fine earthy lady she be, again!
So, in Hartley service, even at QRP output, use the lustiest firebottle ye
can find for most stable operation.

Subject: Regen Tube playings last nite.....
Message-ID: <[email-masked]>

With some of the previous discussion of tubes in regens, I got to thinking
that it might be worthwhile to make up some OT triode replacement sockets
and wire them up for the generic dualtriode commonubiquitoustube such as
the 12AT7 and its brethren.  Those things are as common as flies usually,
so might make a good basis for a plain regen, even in OT circuits like I
tend to run.  After some puttering around the junque boxen I found a couple
of 9 pin sockets and wired them with the sections together as ONE triode
and dropped them into the 4 pin tube base sockets I use for coils and
the like, to make 9A basing to standard triode adapters.  It worked pretty
good, for testing, but was not what I would call a permanent solution.
I had to scrounge the 9 pin sockets, because I rarely ever use the beasts.
I grappled me up an assortment of different pairs of triodes and 9A things,
and set about running some comparisons, by ear, on the BA/GB 80M QRG.
The receiver was my 1925 QST style 2-tuber regen set (detector and one step).
I had locals at 599 and Sandy out in LA at about 569, plus a few others,
so it was a good range of signal strengths for comparison, and ol' 1AW was
just up the band at the usual 59999999999999.  I started off with the '01A
and that was a comfortable loud headphone volume on the locals and 1AW.
Plate voltage was kept at 48 volts for the entire test and filament varied
to suit the type of tube used (from 2.0 volts to 12.6 volts DC roughly).
The '01A was very smooth in the transition into oscillation and not subject
to much hand capacity effect.  The '30 was slightly louder than the '01A
on the locals, but not much different on the weaker stations.  The ease of
regeneration was also very smooth in the transition, and nil hand capacity
effects were had.  I put in a 12AT7 and WOW, what a tempermental beast!
It was very prone to hand capacity effects going near the dial or regen
control.  It went into regeneration a little ahead of the others, but
was very sharp in the transition to oscillation with a pronounced click.
Also the range of control going into oscillation was very narrow on the
knob (maybe 1-2 degrees), compared to maybe 10 degrees or more on the
'01A and '30 tube.  I subbed a 12AX7 and it was a better tempered beast
with smoother regeneration control but it still had the hand capacity
effect.  I reached for the biggie dualtriodes series and put in a 12BH7A.
It had a little more oompf in the audio than the others, and was about
as smooth as the 12AX7, but had a little less hand capacity effect.
I tried the various tubes with antenna and without antenna (and yes the
regenerator could hear them perfectly copyable, although weak at maybe rst
539 on Sandy, 589 on the locals, and 599 on 1AW), and they all generally
seemed pretty comparable, with a slight edge going to the early tubes
in the less hand capacity effect and smoothness of regeneration departments,
while the modern tubes edged out the early tubes in the sensitivity end
of things, with the 12BH7A as probably the best and most controllable of
the lot.  I need to make up 6SN7 and 6J5 adapters for comparison, probably
to round out the middle era tubes.   So, for use in early sets, even the
modern single-triode-wired dualtriodes will work pretty well, with the
right voltages.  Thus you can use a 12BH7 9A-based thing wired into a
4 pin tube base, with a 6 or 12 volt filament battery quite effectively,
in your 20's style regens.

Food for thought.....

Subject: Swan 400 info
Message-ID: <[email-masked]>

Hello everyone,

I am new to this list so don't know much about who is on it. I'm back
into ham radio after 23 years with
an expired tkt. My old call was K5QYY which I recd in 1958, General
class. Now back on the air with a
bunch of Ten Tec rigs but as always we go back to our roots. Tube type
rigs is what I cut my teeth on.

I have a friend that wants to sell a Swan 400 with ext. solid state VFO
and PS. Both the VFO and PS have a spkr built in. Since I don't know much
about this rig can anyone tell me if it was a good rig? I know 
some Swans had a habit of drifting real bad but he says this one is
stable. He used it on SSB only and I want to use it on CW. So, is it a
good CW rig? Does it drift? Have any bad habits"? Can you suggest any
other good tube type rigs for CW use? I very seldom operate SSB. I don't
want to get into rebuilding anymore because my eyes are failing me.
Operating CW is my joy now. Hope to wk some of you
on 80M CW early evenings.

Subject: Mini-Max QRP Transmitter
Message-ID: <[email-masked]>

Folks,
I've been casting about for a plan for a transmitter to complete my homebrew
station and found what I think is a pretty decent one. It's called the Mini-Max,
and is described in the August 1990 issue of The Old Timers Bulletin. The Mini-
Max uses any common late 30's audio tube for an oscillator and a metal 6L6 as a
final. It utilizes a pi-network to the antenna. It has coil winding data for 6
bands, 160, 80, 40, 30, and 20. It is crystal controlled. What I think is really
neat about it is that it is designed to utilize a chassis of a working BC receiver,
transformer powered, as a power supply. One simply removes the final audio tube
from the BC and install it in the Mini-Max, and plug in the power cable from the
Mini-Max into the audio socket for power and sidetone generation. Headphone socket
is provided in the Mini-Max. It is rated to put out about 9 watts and was designed
to be used in the AWA Old Timers annual CW contest. The designer and author of the
article is Keith Kunde, K8KK. The design was taken from a '60s QST article, accord-
ing to Keith, and modified to conform more to late '30s standards.

     The construction details are pretty good and it looks like it would be an
easy rig for a newbie like me to build and use. It's worth a look. The back issue
is still available from the Antique Wireless Association at:

AWA

2 Walnut Place
Apalachin, NY 13732

It's Vol 31 number 2, and it runs $3.50, I think. I ordered it just about
six months ago so its probably still available.

That doesn't surprise me too much, since the 12AT7 is a high gain tube 
designed for TV/FM RF applications.  High gain and high frequency 
capability always spells tempermental in my hands.

>...I need to make up 6SN7 and 6J5 adapters for comparison, probably

I'll be interested in your results for the 6SN7 and 6SL7 (also 6C8G and 
6F8G <6SN7 innards> if you wire up an adapter for them, since they have 
a nicer period look).  Also whether there's any difference between the 
6J5 and 6C5.

I wonder if there's a specific reason (such as the very narrow control 
range you mention) that higher-gain triodes don't seem to have been 
used much in regens.  For example, I've never seen the 6SL7 in a regen.

Thanks for reporting your results!

Hi Bob and welcome to GLOWBUGS! It's good to see you here.

I like to build old style CW xmtrs of the simpler cvariety but I have 
also a few firebottle gadgets of a commercial nature lately.

As I remember the SWAN 400 it as a newer rendition of the SWAN 350 
with some improvements. The front panel was more stylish, but used 
plastic some places that the 350 hadn't and generally looked newer 
but cheaper to me. I think they did improve and stabilize the VFO 
somewhat, but I have never owned or operated a 400. They used to have 
some for sale at the store where I bought my ham supplies in Mount 
Juliet, TN in the 1970s, which I  think closed down long a go.

Again, I THINK I am picturing the correct rig in my mind here...

Your mileage may vary.

Jeff what a good idea. Now me and the son won't have to be so

This sounds like an interesting beast, John! I like metal 6L6 tubes.

Does it use a PI-NET output tank or link coupling or what?

For some reason I can only get about 4 watts out of mine. I think the 
plate voltage might be a bot low - at 250V DC.

Let us know how the project goes!

I just picked up and ELDICO RADIO CO. of NY transmitter that uses a 
6AG7 and a 807 for 60 watts input. The crazy old thing uses
plug-in coils with LINK COUPLING! Only came with one set of coils.
A coil for the grid and a coil for the plate, he he! OLD lo-tech 
design!

Robert, the Swan 400 is a pretty decent SSB rig.  It was one of the
early Swans and was available in the mid-60's.  Because of the VFO being
external to the rig, the Swan 400 actually should have somewhat better
frequency stability than the 350 and 500, all of which used essentially
the same VFO.  Frequency stability of the Swans varied somewhat from rig
to rig and band to band.  My Swan 500 from a cold start just varies a
few hundred hertz until it's fully warmed up on most bands.  On 15
meters though, it varies a couple of kilohertz and even after warm-up
continues to vary just enough to be noticeable.

There's not really much to recommend it as a CW rig.  While I've never
had a 400, I believe the 400 has the same 2.7 kHz wide crystal filter as
the 350 and 500.  CW filtering was accomplished with the addition of an
add-on audio filter which mounted inside the 117XC power/supply/speaker
case.

As for CW use, a Heath SB-102, SB-101 or HW-101 with CW filter installed
makes an excellent CW radio.  These radios are often found in the $100
to $150 price range.

Good luck.

Bill Sorsby, N5BU

In a message dated 97-03-04 18:57:55 EST, you write:

<<  when I tried it the PVC came out without 
 the slightest hint of warming.  If I knew of some other 
 easily-available (key phrase) plastic tubing that had the right 
 physical properties I'd try it, but we should also remember that our 
 predecessors often used lots worse.  BTW, I've also heard the grey 
 (UV-resistant) PVC is not as good as the white, due to the additives 
 used in it. >>

I get polystyrene tubing in 1" or 1 1/2" size from "ACME PLASTICS".  No
kidding, that is their name.  It's a national firm and should have an outlet
in most larger city's.  Look them up, they have it in four or five foot
lengths and its not too expensive.  Its easily cut and drilled etc and looks
better than that PVC pipe.  Of course its RF loss is practically zero. you
can glue it to an old tube socket, using some of the smaller sizes to build
it up to the correct inside diameter.

The Drake Twins make real good CW rigs but are not full QSK. THe RX has
nece 500 HZ LC filtering that sounds real nice on CW. It is also capable
of the WARC bands with aux Crystals. I have a T4XB/R4B and it is nice on
CW. It will o[erate transcieve or split with split being nice for CW.

Any of the R4/T4 a-c make real nice cw stations.
