Here are the guts of 2 stereo Calaf amplifiers.
All of them had exact same problem, bias board failure. Otherwise these are working boards.
You don't really need the over complex bias boards, instead you can place a normal adjustable bias circuit with a few components.
You get:
-3 complete boards, one gutted. 2 boards have also the copper heat spreaders in place.
-3 bias boards, which can be used for reverse engineering the circuit. Otherwise the schematics are available in the internet, except the bias board schematics.
-Power transformer for 2 channels
-1 power supply board for 2 channels
-pre cut insulator pads for 2 channels
Output boards have genuine Toshiba 2SC5200/2SA1943 matched pairs. All together 21 matched pairs. Also you will get 24 PC's 10000uF/80V Nover capacitors.
I'm asking 200€ for the whole pile or reasonable offer. Can be shipped almost anywhere.
