Hi Lee:

My XLSC has a problem. With the FX loop button on the back disengaged (no FX loop) the distortion channel isnt getting to the power amp, while the clean channel still works loud and fine. If I jumper across the FX loop with a cable and turn the loop on everything works fine.

Any idea what component is toast? Also, my amp tech was asking for a schematic of the amp. Do you have one?

Thanks for your help,

If anyone is thinking of new tubes for one of these, I bought Sovtek 5881WXTs and Tung Sol 12AX7s per Lees recommendation. They sound really really nice!
