Cary V-12 blowing capacitors


Hi,

I have a pair of Cary V12 monoblocks one of which is blowing capacitors. It was initially sent in to cary as it was the 3 Amp fuses. They initially replace the capacitors and sent it back. It worked briefly and then started blowing fuses again. It went back to Carrie and this time they replaced both transformers. It did work for a couple of weeks but yesterday when I turn it on and was in the standby mode I heard a crackling noise from inside the amp and 3 amp fuse blew again. There was a large puddle of oil in the back of the amp which is from the capacitor. So it seems like something is still not repaired correctly which is causing the capacitors to blow which maybe is why the fuses are blowing. With it being to cary twice and they are not really sure what's happening has anyone else had this issue?

At this point Cary has replaced the original Jensen caps with the mundorf caps. They also put in a new big transformer as well as the output transformer. They did the caps the first repair and the transformers the second repair. However after the new transformers were put in is when the caps blew again.

@whataboutbob1 Again, I'd suggest contacting Dennis Had, he designed V12. Nice guy, very helpful, he's the singular expert to get to bottom of your problem. Obviously, Cary hasn't effected solution, contact Dennis, he's still designing and building SET amps, low key one man operation,  selling on ebay.

One week ago I installed 36 Golden Lion KT7
7s ( I have a stereo and the two mono block V12s). They're still new so I think they will sound better as we go along, but I am already thinking they may sound better than the rubies. I've tried several other tubes but haven't liked any better than the rubies to date.

I would love to be able to reach out to Denis Had. Do you have a way to reach him?
