Clearing out time, I no longer do much listening, so time to move this wonderful amp to a new home. Tubes have about 50 hours on them. It performs flawlessly, no hum or hiss just dead silent. Very nice cosmetics with maybe a tiny spot hear or there but basically very very clean. Has sub out which I find very useful. No remote, I use an old Logitech universal remote if I feel lazy. I will include a copy of the owners manual, schematic and parts list. And dont forget, it is a bit old, but Audio Research is built like a tank, weighs in over 40 ponds. Great sounding amp.

AUDIO RESEARCH LS-10 PROGRAMMABLE LINE PREAMPLIFIER Not working- for parts or repair by qualified techAlmost perfect physical conditionOne of Audio Researchs high-end and very expensive preamps when it came out in the late nineties - priced at $5500.00 Dimensions- 19 wide x 15 deep x 5-1/4 highWeight- 23 pounds

A very rare and beautiful power amp from the king of vacuum tube technology for 50 years. I purchased this a few years ago but it has been used sparingly as I was able to secure two Jadis units for my 2 main systems nevertheless it is a very musical and engaging piece that never fails to convey emotion. I have been using this for the past few days and it works perfectly. Shipped with original Svetlana winged c 6550 outputs that test strong on my tv-7. Quiet and detailed and I believe it sounds a little bit more like the earlier ARC offerings without being syrupy. Shipping will be a flat $90.00. check my feedback and bid with confidence. thanks listed on other sites so auction maybe stopped at anytime...

The Amp Powers up and works but has a bad hum. It has blown resistors in the past as well as had a shorted trace. All have been repaired. It needs tobe gone through to determine what is causing the hum.Sold as is , no returns.This is a wonderful Amplifier when it works properly.Thanks for looking.
