Hi folks I got a problem with this model 60 I'm working on right now. The set has been re capped, and I had to rewind the primary on the antenna coil.
I was able to peak the IF at 460kc, but when I try to peak the high freq at 1400 I only faintly hear the tone at the middle of the dial around 980 or so and adjusting the antenna or the HF trimmer on the tuner barely make any difference. I haven't made any adjustment to the wave trap, I'm not quite sure how to do that or if its even needed. I'm using my VTVM connected to the plate of the 42 as an output meter.
Anyone have any suggestion where I should look?
This is the correct schematic for this set: (click for larger pic)

Thanks!
