K&M Custom (Two Rock) Question.....

Post by Corymeister »

Hello,
I am a bit curious.....

I opened up one of my K&M Customs because a mini toggle went out and saw two small blue cts trimpots on one of the circuit boards inside the amp. Anyone know what they are and or what they do?

many thanks from a newbie!

1) Don't touch anything in there if you don't know what it is. There are caps in there that retain a lethal charge even after you unplug the amp.

2) Those pots are probably to adjust bias voltage, but could be something else. It's hard to know without a schematic or seeing it.

3) Close it up and take it to someone to get it fixed. See #1. Don't be penny wise and pound foolish.

Somewhere around tthe 3 minute mark there is some decent playing to demo this amp. I was unfamiliar as others might be.
