Re: Problem with a Fisher 400

Have you done anything with the general low-value caps? Mushy... betcha
several leaking caps in the tone control section. Lack of precision...
several leaky caps in the driver section.

Crackling... Mpffff. If on FM, sounds like silver-mica disease. Let me
know, please, the precise etiology of the cracking, from onset to
smoothing, and if it cycles (repeats) or not. Is it FM or all sources?
This _is_ important.

Are the "bad" artifacts confined to one channel or not? Do they switch
with the tubes when you switch them? What is your source (do you use a
source other than the Tuner section)?
