FENDER SUPER 60 problem

This is an older amp, right? So you must've gotten it from eBay or something?

I'm thinking maybe turn it all the way off and let the tubes cool and then reseat all the tubes you can get to. Just pull them out and push them back in again just to make sure the little pins are making good contact. Might've loosened over the years or in shipment.

Tube amps are normally pretty robust, so it might just be a bad or old tube. The rest of the unit's most likely quite okay.

When you turn the amp on, you turn the ON switch on, and then the standby switch, right? I think those amps have a standby. When you do that, do all the tubes light up / glow? If one or more are out then you might get a set of tubes and replace them. From what I could find it's an 80s era amp so it might be good to do that anyhow. I don't know what kind of tubes this amp has, but you can maybe look in the manual or look online for what types they are, then look online (or locally) for the same type. They shouldn't be too hard to replace yourself so it would just be the price of the tubes.

But all you're getting is a buzz or hum, right? Even with nothing plugged in? Or, if you have your guitar plugged in, there's absolutely no sound coming from the guitar, right?

Hope this helps.

Could be a couple of things. Anyway you could unplug the main speaker and plug another one into it. Bad speakers can create a buzzing sound. Without really hearing it everything would be a WAG. (wild a** guess) That's where I would start. It would eliminate the speaker if it still made the same sound.

thanx. the speaker is fine because i use it with my carvin x-100b head. i bought this amp at a yard sale for 5 bucks. an old lady was selling it it was her sons. ill try switching the tubes it has two 6l6 and three 12ax7's. ill keep you guys posted thanks.

If your guitar is plugged in and its buzzing can you still hear your guitar?
Here's a few more first thoughts.

Preamp tubes bad or Preamp power bad.
Tube going microphonic - most often first preamp tubes.
Wrong polarity/ incorrect hookup of a replacement output transformer.
Open, shorted, or failing resistor or coupling capacitor
Faulty signal wiring
Low signal tube bias is pushing it into saturation or cutoff. Measure operating voltages on the preamp tubes. The problem section will have tube pin voltages that are 'way off normal.
Failing coupling capacitors from the preceeding stage.
Failing plate resistor, cathode bypass capacitor, cathode resistor, or grid resistor
Power supply problem.

Most common reason for just getting a big buzz is failed filter capacitors in the power supply. The big electrolytic caps, often in a multisection aluminum can.
