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?

It looks like a filter capacitor failed (the one with the screw terminals). If this was replaced earlier, I would expect that it is covered by warranty. If it was not replaced earlier, one would question why they replaced some coupling caps and not the filter cap, after 20 years it would be suspect. A failing filter capacitor can damage the power transformer feeding it. This is well-known; if the power transformers were replaced then the filter cap would have automatically been considered suspect.


It looks like that is the only damage, other than cleaning up the mess.

Send the amp back to Cary and have them fix it under warranty. I expect they honor their work; give them that chance.
