Classe CAM200, owned since new. The amps were stored for about three years. I hooked both up recently and when they were powered on I got pretty dramatic sparks and smoke. Working perfect with no issues prior. Packed original boxes and stored in climate controlled, dry closet. Power cord to Furmann, XLR to preamp. The power chord and XLR tested and are not defective.
Any ideas what went wrong? Looks like the resistors exploded! I'm hoping I can just replace the resistors and give it a try.

If it's R102 and R105 it looks like the source resistors for the lateral mosfet drivers. That's not a good sign, shorted drivers?
The schematic shows 10N20/10P20 -something, but service manual says there should be, or be swapped to, 2SJ79 and 2SK216.
