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.
