Magnavox only one side works

I've got a Magnavox "Imperial Micromatic" Model no. 1ST681A. the service manual says it was issued nov. 1962
The problem is that I can only get it to play through one side at a time. I know that the speakers are ok, I've swapped the wiring around to test this and I can get either side to work but not both. This is the case regardless of playing a record or the radio. I was wondering if anyone here would have any suggestions on how to fix this.

any help would be welcome. thanks

Check the archive posts here. A dead channel could be a number of issues.

It's like saying "my car won't start!!!", and leave it at that. Is it out of gas, bad carb, fuel pump, coil, starter, ignition relay, dead battery, bad alternator (which didn't keep the battery charged). Or, it could just simply be a bad RCA cable running from the receiver to the amp (if you have a separate one).

I don't mean to sound harsh, and don't want to run you away from this board, but your problem is just too general, and if you're not familiar with these old relics or electronics to begin with, then, by all means, take it to someone who knows what they're doing.

If this thing was issued in 1962, I'm assuming it's a tube model, so definitely a cap job is in order which may solve SOME your problem, but with something that old...have that amp serviced. Tubes can glow, but that doesn't mean they're good.
There are alot of knowledgeable folks here, professional/retired/amateurs who love this as a hobby and/or do this for a living, and from what I've witnessed, they freely share their knowledge. You're not gonna get this type of help at your local Radio Shack...they'll only try to sell you the latest smart phone.

I'm only an amateur, reading a gazillion posts from newsgroups over the past 15+ years, downloading all the info I could find about audio circuits, semi-conductors, etc., and have managed to do my own repairs. It's actually fun once you get the hang of it, but I would never want to do it for a living. If you get hooked, you may start buying some Man Toys like scopes, meters, soldering guns, etc. It can get addicting.

Maybe take a closer look at the innards and you may find something like bad connections, etc. Keep us posted. --BB
