Swollen cap in CTS-1200

Recommended Posts

I have two CTS-1200 amps from 2007. I love them!

But.

They both gives a clicking/static/humm out of the speakers, like "50Hz" I think. I comes and goes in level, maybe depending on temperature. It is there also without any input connected.

I looked inside and cap C933 is swollen in both of them. Everything else looks fine.

Anyone knows if C933 might be the problem? Anyone having the schema for CTS-1200?

You hit the issue right on the button! Please replace the C933 470uf 35v cap with a 560uf 35v cap, low esr, 105 degrees. At your earliest before amps fails further!

Hope this helps!

Thanks! My "cable-guy" just did it, and he says it is silent now. Great success.

I found this recommendation of yours in another thread. Did not know about "low esr, 105 degrees." though, I do not know what he used for cap-spec, except that it is 560uf 35v.
