The ddt circuit on this amp is goofy, they use a 4060 opamp with the inputs at -14 to -15V, the spec range is only +/-12V. So it is possible for it to nuisance trip. There is a button on the back to disable the ddt, try that. I've alos had luck replaceing the 4060 with an LM358 whose input spec is not violated in this application

What type of stereo receiver should i buy


Generally speaking it is always better to have separate amp for subwoofers and separate for higher frequencies.
But why do you want to power PA speakers with home/hifi receivers? You don't 90% of features which receivers have. Look for some PA amplifiers and you will get much more power at similar price. Also most receivers have only about 80 - 100 W per channel and this is NOT continuos power over all 5 or 7 channels! Only the most expensive receivers can do that. You can have 100 W for any channel, but not 100 W to all channels at the same time (spikes yes, but not continuously). And 100 W is very little for your PA speakers.
You should buy amp which has the same rating per channel as your speaker continuous power handling. So if your speaker has rating of 300 W cont. / 500 W spikes, buy amp which has at least 300 W, but 500 W would be better.

The footswitch for bugera 6262 valve amp seems to have a logic problem. The clean channel leaves 'lead and reverb' leds lit on footswitch, pressing 'lead' lights the crunch channel on the amp... and reverb...


Hi ! Check and make shure that the cord conections between the pc board on the backplate of the amp to the logic board are firmly pushed in there slots.
Good luck , Stefan from Sweden

Have a peavey-xr-600b peavey mixer amp. i get aloud hum and noise and cracking when plugging speaker jacks.


Hi chillin884

Not a good sign. Something has gone wrong with the output stages of your Peavey. It is not a good idea to continue plugging it in as damage may occur to your speakers. I suggest you take it to a decent music gear repair guy for a look see and give you a quote to repair These heads, like all Peavey gear, are pretty solid and worth repair. Sorry to be the bearer of bad news like this, good luck

Two amp


I don't know why you'd set the Peavey to 2 ohm to drive 8 ohm speakers??? My other thought is... I wonder if the phase is correct. try reversing one of the speaker wires Left or right side.
