The amp will attempt to power up, but the fans won't kick on and it just keeps flashing a yellow light as it attempt to power up but seems to get stuck. The main circuit breaker was flipped, and this all started when I reset the circuit. There are no signs of overheating or any loose wires that I can see so far. The fan itself is free to spin, just doesn't seem to get to that stage of powering up to start the fan.
The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.

then i'm afraid that your main board has a glitch that you can't repair. take it to a music shop they have the neccessary parts to repair this problem and they have the schematics that will show them which chip is faulty. i'm not sure how long you have had this amp but over time the heat causes the chips or tubes to fail. that is the best answer i can give you at this time anything else would just be a gues and a waste of time. good luck

SOURCE: peavey minx 110 no sound from main speaker but
Inside the headphone jack is a built in switching mechanism. It is there to cut off the sound to the speaker when you are using headphones to practice quietly. For some reason or another it seems as if this is no longer working correctly. One of the causes of this can be bad solder joints on the circuit board where this jack is located. Another cause is a failure of the jack itself. If you are capable, Take the circuit board out and have a look. Hope this helps.
SOURCE: Wires to main speaker are, Yellow & Blue
Yellow should be the positive. Try plugging in and reversing. The louder of the two is the one in phase and the correct wiring. If the speaker is pushing out when playing , it is in phase and correct also.
The distortion problem could be a speaker going out. It may not be totally blown, but may be verging.
Holding your hand out as wide as you can push against the speaker lightly. If there is a rubbing or scratching sound, the speaker could be damaged.If it moves freely, and there is no scratching its okay.
Another possibility is the clean channel may have a channel volume set to high. Make sure the clean channel volume is set lower than the master volume otherwise you can get distortion on that channel too.
Good Luck.
