    CR-820 HOT MESS! Did I get hosed on this one?

    I don't think your measuring voltages correctly.. You should only have +/- 42 vdc at the collectors. And zero volts at the speakers while the unit is in protect mode.

    CR-450 no sound, and blows fuses

    Yes.. They appear to have the mica sheets in place. With your multimeter. Measure the resistance between the center pin or metal tab to chassis ground of all eight of those transistors. Should read " open " .. If any read a low resistance - remove and inspect the mica sheet for damage.
