[R-390] Resistors

[Bob kb8tq]

Hi

Metal films are fine in the audio, IF, and bias sections of the radio. If you get into a resistor that is in the RF path, use a carbon comp if that what was there originally. They are a bit weird in their RF performance and it’s hard to duplicate their characteristics.

It needs a little TLC to get it going and I was wondering what the group recommends for replacements for the carbon resistors?  I've found a few in the AF deck that are out of tolerance and wondered if I should go with the Ohmite OY series, metal film or ?
