Question about Pyramid 10 AMP 13.8V POWER SUPPLY Car Audio Amplifier
I replaced the four 2N3055's in the back of unit but now instead of 13.8 volts its doing 19-21 volts. What did I do wrong? Something in the wrong Place?
Check the resistors that bias the transistors, and also any zeners connected to them.
