Im a little further along on this.
Tube 42 was no good, After replacing tube 42 I had a low hum then touching the screen cap got a loud buzz.
I bought a EICO 320 on E Bay I had to do some work to it. When setting up the signal generator I was able the get a tone from 6A7 screen cap.
Question here is it gave me tone no matter where the generator dial was.
All the coils check out except IF transformer I get 49 Ohms instead of 85 Ohms
Any ideas what I should be looking for? It's a run 7 the last run made.
Thanks, Ralph
