I have posted the schematic and parts list of a 50s regenerative receiver
(224 K) on a.b.s.e., which I received from Colin, K7fm, This receiver has
been discussed on boatanchors.

It is part of a construction article, now a 4.7M pdf file, which I will post
if there is any interest for it. The project receiver is fairly typical of
what someone in the 50s might build as a shortwave listening receiver, or
for a beginning ham radio receiver.

To pique your interest, the detector uses what is a modified Hartley circuit
using an unusual selection of tube.

In the .pdf file, there is a 5Y3 tube power supply schematic, of 50s
overkill design.
