Another silly question, do you have some cans plugged in? That can disable the outputs.

No doubt Bill. This one has my curiosity going. Pre-outs don't just magically stop working. It's most likely something fairly simple, yet overlooked. :-k
In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.

Even if it's that, I would hate to see him get rid of it over a $3.00 part and a couple minutes work. ](*,)

hmm don't see a mute switch anywhere, but if it was muted then the light on the knob would be red right? Also, what does Bill mean by cans?

I would hate to get rid of it too but its driving me crazy how the pre-out will not work and the popping in the speaker when I press some of the buttons leads me to believe that something is not right and I'm baffled!

Get back to the forum about the headphones, If nothing else Ob156 will get you in the right direction.

Can you see if TC9215P is socketed? If so, I'd just replace it and see if that makes a difference.

Ok so I took the lid off and it seems that its a little risky trying to get to that particular circuit due to its on the bottom. Anybody know of any good audio repair shops in Cali? lol

With things being as they appear to be with your CT-17 I would personally consider only 2 options at this point. There are only 2 places I would send my carver gear to have it repaired which would be Mr. Carver himself, or Rolland. First I would do is find out what the charges would be to have your unit fixed. Then I would look at the cost of repair VS. replace and weigh your options at that point. If the repair cost makes purchasing a replacement unit your best choice then shop carefully. While you are shopping for a replacement unit one my wife has a super nice pre-amp you can look at as part of your shopping adventure. Sincerely,

yeah I was thinking about that but $175 is a little too much for me right now, how much does Rolland charge?

You have to CALL Rolland to get a price quote over the phone.
