So I bought the Reference One preamp new about 20 years ago and it has just worked.
But yesterday it broke in a very weird way. It was powered off but I looked over and saw a number of lights on. The volume and balance knobs have lights to indicate the level, one light on at a time. But the left side of both were all lit, not fully rather dimly but definitely lit. The power light was on dimly as well. I tried toggling power and it had no effect. Finally I removed power cord and plugged it back in. Well the lights are all off but the preamp is dead and does not power on.
I am lucky I live in california and have 2 arc authorized repair places within a reasonable drive.
But I am a bit worried about how expensive this might be. Have any tube experts seen these odd symptoms before and if so what is the best guess of the damage? Thank you.
