Levinson JC-1 - CJ 10b = blown Yamaha M2?
Time to fire up the stereo.
Pink Floyd - "Wish you were here" seemed like a good test of my new CJ 10B. Hadn't tried anything quite like that yet.
Got into the intro, everything seemed good, the lights in the room dimmed for a split second, the Yamaha M2 went quiet for a second. The right channel of the power amp is now gone. I tried switching the leads from the CJ, still have a signal to the left but no right.
Being fairly adept with a screwdriver, with cover removed, I found not a fuse in sight. I had for the longest time noticed a bump, if you will, in the right channel a few minutes into listening each time the Yamaha M2 was fired-up. I suppose the bump has now bumped for the last time. I think you would agree the amp is not worthy of repair, but don't want to do the same thing with a new amp.
In using the CJ phono stage, I found a need to use my Levinson JC-1 cartridge preamp. Without it the Supex sd9000 needed a lot of volume attenuation. In that I was listening to an album at the time of the catastrophe, did the use of the JC-1 cause the right channel to let go some how?
I wonder did I foul-up by hooking the Mark Levinson JC-1 to the phono input of the 10b?
Without the cartridge preamp I found it necessary to turn the volume control well past 12:00, with the Levinson only to 9:00 or so. The preamp sounded great prior to this episode, I can't believe the CJ created the problem. I would certainly appreciate any comments.
