I've got to replace the Citation 22 which I use to power the woofs in my JBL L-300 Summits (biamped setup). I don't think its worth the $275 estimate to fix, given how flakey the 22's have been. I'm also tired of getting burned on used amps/preamps on eBay.
So what about the Parasound HCA-1000A or the B&W 125.2??? Would one be better than the other in the <800hz range?
I'm looking to spend about $600 plus tax and license. Any other recommendations? Thanks in advance.
Post what is wrong with it here and see what everyone recommends.
Don't throw it away. At the very least part it out.

I definitely won't throw it away. Probably put it back up on eBay (with full disclosure) for $100. Both channels still work, it's just that there is low level intermittant noise on both channels from time to time. Always at start up, then can clear up a play fine for an hour and get noisy again. Noise can be "pink" noise transients or whistling.
I'm an old Heathkit-Hafler kit builder, so I could replace a known bad part, but have no trouble shooting experience or equipment other than a digital volt meter and a soldering gun.
Did they tell you what was wrong when you got the estimate? If'n you were a couple thousand miles closer I'd loan you a scope.

Sounds like an aged part, potentially a capacitor although output transisters can exhibit this behaviour.
If its both channels and you are certain its not comming from the source start looking at the power supply. If there is mains supression capacitor have a look at that.

It's definitely not a source problem. I disconnected the inputs to verify that. <O</O
The noise is never simultaneous on both channels. It can be one or the other at any given time, with the noises I described above. <O
The shop never did take a look at it. They just said their nominal repair bill on a large power amp is $250 to $275.<O
I wish you guys could stop over and take a listen to it. Anyone got a Starfleet Transporter??
