This should really be posted to the Boatanchors reflector!
I have a Chelsea Transcontinental that uses the classic Armstrong
regenerative design and 3 '01A's. I have never found a diagram for it, but
there are many 3 tube regens from that era that are all virtually identical.
A look through an early Rider's manual will find you several similar radios
that will give you a start. The circuit is VERY simple with only a couple
of caps, resistors and interstage transformers.
