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

No output from channel B. Slight crackling, but not a dirty potentiometer. A dry joint or easy fix?


Start out by doing some simple troubleshooting yourself. You have one working channel so substitute the cables from the working channel to the nonworking channel to see if you have a cable problem.Check to see what button settings you have on the amp. One might have been changed by accident. I am assuming your are wired up for stereo and not mono.. Here is a link to the manual if you don't have one:http://www.peavey.com/assets/literature/manuals/80300573.pdf I should also have mentioned to substitute the speakers from the nonworking side to the working side to make sure you don't have a speaker problem. Notice in the manual that it states that the DDT compression switch should be enabled at all times to protect your speakers. Also take note of page 3 Operation notes for both the thermal protection and the DDT circuits. Amplifier failure is usually caused by the failure of another component most often cables and speakers. If a dead short (broken cable or blown speaker) is presented to the amp it may fail no matter how good the protection circuitry is. If the simple tests I mentioned don't help I recommend taking it to a Peavey dealer with a good service shop as they will have access to Peaveys direct replacement parts. The schematic can be obtained but for a proper repair the direct replacement parts should be used. Peavey was one of the brands I serviced when I was still working as the service person for a music store. My eyesight has deteriorated so I am semiretired. Hope this advice helps.

My peavy has three lights at power on when in use red light comes on is that beacuse my amp is overheating or is it normal it does that when i crank the volume amp i not hot well vented


Here is a link to the manual:http://www.peavey.com/assets/literature/manuals/00512180.pdf Page8 sections 2 through 4 discusses the LEDs. I think what you arte talking about is the DDT active LEDs. Page 12 specifically discusses this and page 15 notes that Red signifies DDT clipping. Peavey recommends that you don't defeat the DDT circuit and that is good advice as it protects your amp and your speakers. The clipping is not caused by the amp but by the amount and quality of signal being input. Check earlier in your signal chain for the cause.

The DDT light on one channel stays on,but I can't find a reason why? What can I do?


Disconnect the speaker wiring and speaker on the bad channel. Turn the level control(s) all the way counterclockwise and turn the amp on. If your DDT (limiting) light remains lit, it's time for a visit to your nearest certified Peavey service center....G.

I have a Peavey PV2600 amp that had some blown outputs, open resistors, & burnt misc. components. I have replaced all the parts, but now I have the DDT light on steady for Channel A even with nothing...


Chances are you have NOT got all the bad parts out yet.

HINT: While cold starting an amp after it smoked, put a 150 wat lamp in series with the power cord to act as a current limiter... saves fuses and parts.

The DDT circuits PROBABLY look for amplifier DC balance AND no overload of power supply as protection.

They COMPRESS the audio when it goes above a certain level.

SO, to troubleshoot this you will probably need an oscilloscope.

LOOK for a supersonic oscillation that you cannot hear but MAY be driving the amps beyond the DDT trip point. Drive a pure low level sine wave into the amp and follow it through to see at what point the DDT compressor senses an out of range level.

Remember it HAS worked before, and there is still a bad part in the unit. DO use my suggestion to limit the current as often while troubleshooting this type problem, the signal will suddenly go to a point to fry something, then you get to replace all the parts AGAIN.

Peavey PV 8.5C DDT is activated on channel A even al low volume, channel B works fine. All 8 power transistors on both channels were found OK. Driver transistors and 15V zener diodes are all OK as well....


Check your speakers and Cables. I had some speakers that traveled in my small trailer and the vibrations of the trailer caused the diaphram to back off my horns. Once I got the speakers fixed the DDT light on my power amp stopped staying on so much.
