Replacing 2N2147 Germanium Power Transistors In A JBL SE401 Transducer Energizer

[NVGrampy]

I Have owned A JBL SA660 Black Integrated amplifier for over 30 years. It has the same problem with the output transistors. I do not want to modify this amplifier so I just use it as a showpeice.

Thank you for your note. A friend if mine, Steve Hogan, spent an inordinate amount of time with me re-designing the output stage with Si Power Transistors. It might have worked well. Then, the pandemic ... This is now in a bankers box.
