Dead peavey supreme XL amp head

My friend gave me a peavey supreme head that didn't work, so i offered to take it hoping it would be something really easy that i could fix. i plugged it in to an outlet hit the switch, nothing, the led "indicator" didn't turn on. so i opened it up, checked the fuse, good, checked for any frayed wires, nope, checked for any burned or suspicious looking components and circuit board, also good. i haven't gone any further because i don't know if i want to dedicate my time. i would like to test the transformer but i don't know how. i have a good feeling it is a power supply problem, i was wondering if any anyone has ever had this problem or if anyone knows any test points that i could measure with my multimeter ?

It's an amplifing unit, it has no built in speakers, but the led indicator doesn't turn on which leads me to believe their is no power flowing through the circuit. Theres no tubes, it's a solid state amplifier (transistor).

I'm not a pro on amps but I have a Peavey Rage 158 amp, I'd suggest seeing if the speaker itself still works by directly connecting a source onto the speaker[take the wires off and hook it up to a source].

Try turning it on and checking the wattage going to the speaker wire, then follow the wire back and check the big coil with copper wire among other things.

A common problem with old amps are the tubes, check the tubes to see if they are burnt out [google it if you need a guide]
then check on ebay or maybe an electronic/guitar store.

If that didn't help, reply with more details

Good luck.

[If you don't want it ill take it off of you for $20 :p ]

Do you have the Impedance switch set for the right cab?

Are you using a guitar cord to connect to speaker cab ?...If so, dont. Use a speaker cable.

Is the damping switch loose?

Peavey 2600 Low input = Complete Cutout


I'm not quite sure of how the two amps are interacting here, so I'd like to request that you describe the entire hookup. Sending a higher signal from the mixer should not be a problem, but something is wrong in the setup (I think). Please update this with a description of how you have the mixer and amps connected to the speakers. Thanks, Dan

Peavey 8.5c amplifier. One channel dead. In


FIrst of all, in bridge mode there is only one channel. The "bridge" means that you combine the two channels together to get a single more powerful amp. The swollen part is probably nothing. Sometimes the plastic caps cup like that. Unless there is a specific problem with the amp, don't worry about it. Try placing the amp into stereo mode and testing each channel. If both work, there is no problem with the amp. If for some reason you need repalcement capactors, contact Peavey directly. They supply replacement parts.

Peavey TNT115 AMP cuts out


The problem is in amplifier section caused by change value resistor or leak capacitor or cold ,loose or crack solder joint parts this the common problem of over heating and shuts out the amplifier caused by abnormal distribution of current,try to check all the capacitor and resistor and replaced the defected parts ,so your receivers works normal again.

Hope it may help you;

Crate BV120 too quiet


Have the tubes checked when good and warm.
Check for any leacking capacitors.
Check all solder joints are shiny any that are dull try to reheat and apply solder.
Good Luck
