Blaupunkt car radio Bamberg CR stereo 455 7634934210 SN: G5490440, Amplifier 8638710305 SN: 0755865.
The amplifier contains 4 parts I can't ID W700, W710, W720, and W730 all custom IC's?
I need a schematic on this (rare) amplifier or at least pinout of these parts?
These units also came with a UKW Stationwahler 7607127000 SN: F0489781.
Thanks for any help.
