Well, I accidentally blew out channel 2 on my dc300a.I had just finished changing a couple of caps on the main board and was trying it out when the faceplate accidentally touched the heatsink on the corner transistor on the main board. A loud spark and now 60volts dc at the output. Goodbye speaker and goodbye channel 2. Where do I start? Did I avalanche the whole side? The diodes on the ch2 board read ok. As do the resistors.  Should I start with the predriver transistors?  I have traced signals thru guitar tube amps sucessfully but transistor amps seem too confusing to me.  Should I send the amp out to be fixed? Any help will be appreciated. Thanks, Cronie

I need to exchange the oblong pushbuttons on a couple of ic150s. Do they just pull off? Can they be broken pulling them off? Any help will be greatly appreciated. Thanks,   Cronie I just pulled a few  off  but one of the white pieces they pull off from is broken. Can this be fixed?
