I built this amplifier circuit. The voltage readings on the power transistors start dropping after a few seconds and the current draw on the power supply starts climbing.
The power transistors start to heat up. I know that the circuit is built correctly per the schematic. The components are all new and I have replaced the transistors with the same results. I have not injected a signal into the circuit.
See attached schematic.
Any advice would be appreciated.
Would the transistors be damaged from heating up?
