I've just finished recabling a Dual CS503-1 because one of the channels was dead. I have continuity from the start of the tone arm wires right up to the RCA connectors but the problem persists. I have reversed the Left & Right connectors to make sure it is the turntable not the amp (tested with two amps). Seeing as I've ruled out the wiring does this mean there is a problem with the cartridge/stylus? And how would I go about finding out short of buying a new cartridge? It has the stock Ortofon/Dual DN249E still, not sure about stylus condition or if it's ever been replaced. (The one channel I have sounds fantastic!)
If I set the balance all the way over to the dead channel, I do get a quiet signal, but nothing at all when balance is normal.
Edit: I just measured the resistance between the two sets of pins on the cartridge (all wires removed). My working channel reads 14.4 M ohms while my faulty channel is 14.4 k ohms. Is this significant? Sorry for electronics noobishness
