Quote from: g1 on March 02, 2021, 07:35:49 PMThese amps with darlington type power transistors are especially picky about proper heatsinking and go into thermal runaway if it's not right.Is the heatsink compound old and dried out? Are the power transistors mating well to the heatsink? Also check that the diodes in the heatsink are placed the same as on the good amp, and whether there is heatsink compound there.Also possible the transistors are fakes depending where they were sourced from.
