Need help with a Warwick BC80 bass amp repair. It's dead. Can't find any schematics on the web. A schematic would be, well, helpful...Anybody??
The amp is based on a TDA 7293 chip amp. There are 2 bigger R's on the PCB, one (marked R24) is alive, and gets hot. The other one (R23) is stone cold, and measures at about 150k, way too high. The markings are discolored, maybe 1k. Can anybody tell me what value this should be?
The amp is presented as a 80 W amp, and although the chip amp _may_ produce it, the heat sink is insufficient, imo...
