You may want to try the Troubleshooting forums for help in fixing this. The premier 3 is a really nice unit and I would try to fix it before tossing it (or selling it).
Conrad-Johnson Premier 3 - worth repairing?
I have a Conrad-Johnson Premier 3 pre-amp that I no longer need. Physically, it's in great condition. I recently replaced all tubes, but the left channel is dead and I'm not savvy enough to fix it myself. I live in easy driving distance to Conrad Johnson's HQ, so I could drop it off for repair. Do you think it's worth investing in the repair and then selling it (either here or on eBay)?
