I have a couple of US Acoustics 4 channel amps that I bought then realized they wouldn't fit where I needed them. The first is a USB-4085. It does have a few small chips in the paint, but it's in good condition overall and functions 100%. THe second is a USB-4065 in near mint condition. Both have the plastic feet, manuals and boxes. Yes, these were built in Korea, but using the Zed USX design with the same boards, specs and performance as the ones built by Zed. The price is $85 eash, or $160 for the pair. Those prices include shipping within the CONUS via UPS ground. Any addresses requiring USPS (PO boxes, Alaska, Hawaii) will cost extra. I'd also be willing to ship them internationally to a PayPal verified address if you're willing to pay for it. PM if you're interested.
