Phun with a 57
#1

Just got one of these today, good solid cabinet and chassis.

First thing I found was that there was no B+ beyond the 80 socket. Most strange.

I found that there was no connection between the 80 and the field coil. I put a jumper in and the radio came to life... well, at least the audio did. It took some doing, but I finally got the IF tuned.

The RF section is another matter entirely. After going nearly crazy, I have gotten that working on the very low part of the band. The LO stops around 740 KHz. Pretty good reception on the one station I get (603 KHz). As powerful as that station is, it's quite difficult generally to receive it without a lot of noise on any radio without a loop antenna, but on this one, it's quite nice and clear. But, as I said, it's dead as a mackeral on most of the dial.

I guess first thing I should try is to replace the 77 and see if it works any better. This is only a 4 tube regen-superhet, so it's not a hot set, and the capacitor count very low, some of which seem to have already been replaced with modern caps.
