Model 77 questions
#7

frankenstein Wrote:Ok well, that explains the unusual schematic. Duh! I guess I need to brush up on my theory! Btw, is there a link as to what to do with these condensors? I don't want to ruin them in an attempt to fix them! Years ago when I was in my teens I was "restoring" old radios, but its been about 25 years since I've done this stuff. (I'm an electronic accessory tech in the auto industry now.) I have done some work with the "newer" old stuff recently; I've reconditioned and aligned a Dynaco FM 3, Pas 3, and ST70. And I've scratch built a single ended stereo amp using a 5U4, 12AX7, and 2 6BQ5's. But, I do not recall anything as peculiar and interesting as this '77! I would like to thank you again for all the help so far and will keep you informed of the progress on this project.

Cheers! Dan

This may not be the exact type used in your radio but will give you a place to start. Many people just disconnect the cans electrically and mount new caps under the chassis. IMO a butch way to do it but it works OK. There are people that will rebuild your cans for you, I have no links at this time though. philcorepairbench.com has lots of good info so look around.

Hope this helps

It's not what you don't know that hurts you it's what you know that's not so.

Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
