Remove IC short circuit pins 1+2 , short circuit pin 9+5

Expect very low or no bias and you need to change resistor or trimmer on the VBE multiplier to achieve bias

Then you got your shelf a typical class AB amplifier ...no more Super class A

Kind regards
Sakis

I can't even find a proper datasheet for this interesting chip.

Must say this type of JVC equipment was of really awesome build quality.

For the record I have 4 of these chips, removed from a working amp.
