Have 3 Carver PT-1250 amps, 2 went out, fans are no longer operational and suspect they stopped functioning prior to the units. Wasn't aware or thinking of the fans failing since they were on low and not really audible, they most likely stopped and the unit over heated. Has anyone experienced a similar issue and what was the point of failure besides the fan (i.e., output op-amps/transistors)?🥲
