This amp works well and no issue. Amp has been used (of course) and has a few cosmetic scratches, but functions as it should. A very nice neutral sound that is easily shaped - and loud. It's built like a tank. I'll add some more pics tomorrow.
I'm older now and I've downsized substantially under orders of the CFO. The amp will come with a 2U SKB rack.
I also have the matching Yorkville 410B speaker cabinet (8 Ohm, 500 Watts) for sale separately. I'd love to move both at the same time.
