Hi Charlie
I have been procrastinating on the doghouse. I see two shielded leads and a couple of cloth wires to be disconnected to get it off. But I can't put it off any longer.
The alignment part is the thing that is baffling me. If I do not use a .01ufd cap between the sig gen and the pin 1 of the if can, (even though the manual does not describe that) I am connecting to 275vdc, and certainly going to burn something up. I am injecting 50kc unmodulated signal, but get no speaker output. I do at 1500kc, and at all of the dial calibrations.
Thanks Ken
