GK 250ML Series I with issues

[kissfan113]

I have a Gallien Krueger 250ML series I combo with some problems, the Led doesn't light for the echo channel and the chorus will drop the signal to a whisper when engaged and doesn't seem to effect the signal in any other way. Id like to get this amp up and going to it's full potential if anyone has any knowledge about them.

Never worked on one but I have the schematic.

That would help for sure MarshallJMP

No problem, let me know if I can help out in any way.

I have the same combo, I sent mine in to GK years ago, and they got it up and running again. They're pretty good little amps. I've played a lot of gigs in the mid 80's with mine. They work better in a live setting when plugged into external speaker cabs.
