So, all dead transistors replaced with appropriate equivalents, and the amp was reborn. Success, and very much worth the effort! We’ve covered a lot of amplifiers here in the past.

Arduino Uno with LCD/Buttons shield on a breakout board. the area occupied by "ca1" shows each test combination that is tried and whether there was conductivity (1) or not (0). ca was the last attempt ...

This amplifier is a further development of "Versatile Audio Amplifier with the Current Output Signal". In this version I gave the input transistor T1 more linearity by using a MOSFET transistor BSS110 ...

Single transistor holds the potential to power a high-performance amplifier with the right components and setup. By following precise techniques, this transformation enhances audio output ...

There were 2 different #s on the output transistors, but he said they started using all 44s later and I could just replace them all with 44s and it would be fine.<BR><BR>I hope this works, I am ...
