Hi There,
My 1950 Zenith cobratic is having trouble with the sound. It was fine last night and then the sound didn't totally go, but it went very low. I can't get it to work correctly. Any ideas of what the problem might be?

Without having it in front of me, it's impossible to diagnose.
Just like having to go to the doctor to find out what's wrong with you.
It can't be done over the phone or online.

But, alas, if the thing hasn't been restored fairly recently, it would definitely need that.
