Peavey KB 300 no volume at first turn on

Post by Roger T » Mon Jul 26, 2021 12:33 pm

I have a Peavey KB 300 I use for my one man band performance. It's great w/3 imputs for mic, drums, and guitar. Sometimes, and you never know when it will happen, it just has10% volume when it's first turned on. Then after shaking it, or running the volume knobs to the max and down a couple of times it comes to life. Don't know if it's the volume pots but in dismantling it I might make it totally unworkable. Naturally if I take it to an amp tech guy it probably will never NOT work so the repair guy can actually see the problem. Any Ideas or someone w/the same problem?

Next time it happens, poke a plug in and out of the POWEWR AMP IN jack a few times. Any help? Also ty a spare cord plugged into the PREAMP OUT JACK and into the POWER AMP IN jack. Any help? Any model of any brand that has loop jacks can have this problem. VERY common.
