Appreciate you sharing your findings.I also have a V12 and have had this problem,however in my case it was the slow blow fuse.Having said that you never know what suprises await down the road.
Question about Cary V12 amplifiers
I purchased a pre-owned Cary V12R stereo amplifier (recently re-tubed). It sounds and looks great. One of the 'good health' LEDs for a pair of output tubes on the left channel, however, is no longer lit. The tubes appear fine, and I don't notice any sound degradation. Before I adjust bias or purchase tubes, does anyone have any comments or suggestions?
