Hi,
I have a Spectron Musician III SE mk2. The right channel started acting up. No sound from right channel when powering up, but the sound would come back if I play right channel only and spike up the volume. Then two good channels could last for a few weeks or months if I leave the amp on. Anyone knows of a repair shop in San Diego or Orange County or LA that could fix this? I can sell the unit as well if someone is interested. Just spent $200 upgraded all fuses to HI-FI TUNING SUPREME 3 audiophile fuses.
