Question about Audio Players & Recorders
There should be an 8 pin IC close to the input jack that will be marked 4558 or 4560. This is an Op-amp Ic that is the most likely cause of the problem. Replace that IC and report the results here.

I just bought the Vintage Club 60 and am loving it. $300..Pretty good deal huh! Plenty of bass...Have you tried the low boost and mid boost switches? they completely change the way the amp sounds. Also the stock speakers are **** so I'm dopping some Celestion Vintage 30s. Also is anyone getting some tube jingle with the VC60? I'll probably have to take it to someone...

Even though I don't have a schematic, if you have a VOM, (Volt-Ohm, Milli-Ammeter) we can start. Just because tubes are old doesn't mean they are used up. If a tube doesn't light up that would be a bad one, but they are in parallel off a winding of the power transformer. 1.) Check the on/off switch with the ohmmeter and the line cord for conductivity. 2.) Check the primary winding of the transformer for a low ohms reading. (less than ten ohms). 3.) Some where between the power switch and the pwr. trans. should be a fuse. After these three you should be able to put 120vac. to the unit and bring it back on. Get back with us, Dale

Sounds like a bad cable or pickup. Set the volume to a level that you can
tolerate. You may want to turn off the amp
between each of these steps. Unplug the cable from the amp; if the hum does not
go away you have problems with the amp. If it does then plug the cable into the amp
and short the end that plugs into the instrument. If the hum goes away it is the pick system in
the instrument, if not you have a bad cable.
