Hi: If the Amp has an audio output transformer, check for bad solder connections to the pc board, This are the wires from the transformer to the PC board. Another place to look more...
the back check and replace if blown.make shure power plug is good.check with a volt meter on the input side of the main power transformer.good luckbig red more...
transistors or diodes without schematic hate to go much further ..any pica fuses or such that may be blown? any known issues with power transformer? thanks more...
Getting a schematic for a Bang & Olufsen system My Bang and Olufsen Beomaster 2200 has a dud transformer and I need to know the toroidal power inputs for it so I can get an equivalent one. more...
Scottymac and to all. Power transformer for power amplifier are high current. resistance on both primary and sec are surely very low, one can think its shorted. If all fuse more...
