Yeah, I like GK amps. But it's time to cut down. [DEL]GK 1001RB[/DEL] - (not the II series). In great shape, with rack ears. 565 watts from the main channel. I've never tried the biamp channel, as I have neither the cable nor the speaker for it. $325 shipped. - Sold to TBer Spent [DEL]GK 400RB[/DEL] - the VW Beetle of amps I've heard it called. A little beat up but still keeps going. Love the tone. $225 shipped. - Sold to TBer JimC [DEL]GK 800RB[/DEL] - this one has issues. The main amp works but my tech tells me it will need to be re-capped at the very least. There is some whooshing noise too (it's soft, but may be the precursor to a component failure). The HF amp is fried. Lani at GK says I can buy the latest rev power amp board in kit form for $195 but that's beyond me. If you're looking for a project, this is a good one. $100 shipped. - Sold to TBer Chromedome I've cleaned the send loops on all of these but still run with a cable in the loop anyway just as a precaution.
