This shows the amplifier modules and the power transformer. We could not get the power on by the on off switch so we hot wired power to the transformer.
This is another view of the transformer and amplifiers.
This is a view of the back side of the guts.
So far I have been able to confirm the pins of the amplifiers. There is more to come.

The power transformer has six windings that are 42 VCT each.
I have a single one of these boards. What kind of transformer do I need? And how do you unmute it? It will drive 4ohm speakers.
You need a transformer with 40 to 42 VCT to power it up. The mute is turned off with a resistor to 5 volts.
Thanks
Thanks
