I need to get this amp working. Built similar using TIP 41 and TIP31 transistors. Using the mosfets shouldn't have to worry about parts getting warm as I had one transistor getting hot, changed out and now it works fine
The pic input at R2 is a random square wave.
The junction of R1/R3 is 12v but using 9v (only voltage source I have presently for testing)
Q7 and Q8 are getting hot. Thinking the base resistor might be wrong? but having NEVER worked with Mosfets?
any suggestions
The resistor values were suggested by a knowledgeable individual.
