This model has a breaker on the back did you try that? Have you checked the speaker connections and other connections?

SOURCE: Marshall MG50 DFX makes a squealing noise on power up

Yep, chalk that one up to poor design...The amplifiers are going out of balance during power up and down. Two seconds is pretty long... Try turning down the gain during power on and see if that affects it.

The pop on turning off is normal... None of these have speaker disconnecting hardware that is necessary for very high power amps. The biggies have hardware that checks amplifier is balanced before connecting the speakers and a relay also cuts the speakers immediatley on power down. As power goes up and down the circuitry comes to equilibrium and until it does, strange things happen.

I would investigate the CONDITION of the filter caps for the main power because if they age to a higher internal resistance that COULD cause the high freq oscillation on power up... Two seconds is MUCH too long.

There should also be some non-electrolytic caps NEAR the power output transistors to handle high frequency supply power bypassing.

Check the power bypasses that service the preamp stages. Look for pregnant electrolytic caps that have failed.

Ultimately, you MAY need an oscilloscope to isolate the high freq problem.

The power amp section has blown parts. You will likely find they use a chip like the TDA7293 as the power amp output and it will be blown, shorted causing the fuse to blow. These cost $6 from Digikey.com. Find a competent tech to replace it and use heat sink compound. Verify the part before ordering one. They come with leads bent either way so make sure you get the one with a matching suffix letter. When firing up after repair, put a 60 watt light bulb in series with the hot power lead to act as a current limiter... saves blowing fuses if there is another problem.

I have seen this problem before. If not a valve issue check supply smoothing caps 22uf 500v

My peavey amp pv 2600 only plays on channel A. No output on the B side


Hello,

Check the "BRIDGE" switch position, "IN" for "BRIDGE", "OUT" for "STEREO", and clean ALL back switches with a cleaning spray and then run the amp again, also check the two green lights activation at front, if they activate, then amp is certainly working, let me know further.

One chanel of my pv 2600 amp is playing very low


Hello,

Clean all back switches first of all, use a cleaning solution spray and give a 3 shot per switch, then push in-n-out several times each one and check amp functionality again.

Can one(1) Peavy PV 2600 amp provide enough power for two(2) Yorkvilles 15" 300W full range and two(2) Yorkvilles 18" 400W subwoofers?


It should be able to do this. You would need to put each type speaker on a seperate side and then use either an elctronic crossover or an EQ set to pass only lows into the side for the subwoofer to block sending highs to the subs.

I have Peavey Pv 2600 Power Amplifier ,the B side did not work sound did not come


One side of the amp has failed and repair is NOT DIY. Take it in for servicing. This amp has many components in the power amp and repair is complicated. A failure can lead to 20 components being damaged. Failure to replace all damaged ones can result in immediate failure destroying the replaced ones.

Do you know what regulator/ rectifiers are used and their numerical values so i can repair my fried pv 2600 these are the row along heat sink small black ones 2 pin and 3 pin cheers


7815 and 7915 plus and minus regulators specifically. Diodes fr the 15 supplies are 1N4001 but you can use 1N4007 or anything in between.

Big power rectifiers are 2504's... which are probably 25 amp 400 volt modules.
