Emerson 659B: No FM Reception

[radiotvnut]

I fixed a dead radio once that someone recapped but the soldering wasn't worth a flip. After I resoldered everything, it worked fine. What value electrolytics are in there? It's quite possible that someone put the wrong value caps in place of the original.

BTW, I've got a red AM only version of this radio.

There's a mixture of 'lytics bundled together, disc caps, and what look like Orange Drops. Oh, and a crapload of electrical tape. I believe the electrolytic caps were bundled together to replace the original value of a larger paper or wax cap. What's the model # of that AM-only model, and what tubes has it got? Sounds neat!

I had an Emerson like that one, only brown instead of cream colored. It had notable bass response for its being a table radio.

As for your electrolytic pi network you need to be sure the negative leads are returned exactly where the originals were--not merely returned where it fits conveniently. Also check the state of the capacitor sometimes found in old "hot chassis" radios that connects the common negative line to the chassis. If it is the original it can cause problems--including possibly going off with a loud pop and foil confetti everywhere.

There are very few, if any, original caps now. When you say 'original position', do you mean the actual physical location of the wire? That may be indiscernible by now.
