A while ago there was a thread about chokes and how their core
construction differed from transformers. This week I decided to
build a supply for my AMR101. Needed was 6.3V and about 250V.
I had everything but a choke. So in a pinch I substituted a
30V, 2 amp transformer (use the primary). The thing really
works well - the ripple is attenuated about 40dB. I used
30 uf caps on each side of the PI.
