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?

Your really need to contact Dennis Had, he founded and designed the V12. I previously owned Cary SLM 100 monoblocks, had cap issues, with Dennis' help I was able to effect repair at home. Cary had issues with Jensen copper foils in this era. Dennis still active selling SET amps on ebay, may find his email there.
@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.
Dennis manufactures amps under Inspire name. Check various forums, someone there may have contact info. I see his amps periodically sold on ebay, don't see any at the moment. He seems to be keeping low profile these days, suspect he makes small runs of amps, generally I'll see only one amp available in his ebay sales.
If you're diy, oldhvymech may be on to something, unless you've damaged other parts due to leaking caps. What he suggest is not that hard a repair to effect. If you went diy route, and that didn't solve issue, may have hard time finding tech to work on it, many won't touch equipment that's had diy work done on it.
