Henry,
Been working on a 41-295 also. In addition to checking the tolerances of all the resistors....there are two paper caps. hidden under the audio outut transformer...maybe you found these? They are C70 & C75, .006mfd, coupling caps to the 42's. Also check C19 the 2,000pfd. Micromold cap, part of the AM oscillator circuit. Although it looks like a mica it could be a paper cap if it is a Micromold. Also, check the 3,000pfd. cap inside the 1st. IF can. This was a Micromold 'mica' in my radio but also could be a paper unit! And, check C24/25 the 370 pfd micas on the swithing tuning assembly. This combined unit could be bad..it is an odd looking block cap.
If you have rubber insulated wires into the IF cans they should be replaced also to prevent possible shorts. Lead dressing from the volume/tone controls can be critical.
Best of luck. John
