***PLEASE READ THE FULL DESCRIPTION BEFORE BIDDING AND MAKE SURE YOU ARE OKAY WITH MY NO RETURN POLICY*** Works perfectly! Tested thoroughly prior to listing. I am selling this AS-IS, FOR PARTS/NOT WORKING, because I DO NOT ACCEPT returns on electronic items. Please see photos for detailed condition. Because of this, I am starting this listing at $1 with NO RESERVE. This is the most incredible amp I have ever owned, and it breaks my heart to let it go! Comes in ORIGINAL Factory box, with BRAND NEW factory (China) tubes, all instructions and tools. The sound is INCREDIBLE! Holographic and expansive. Clean and clear and warm. Pushed my power-hungry speakers with EASE. You MUST adjust the bias on this amp ANY TIME you change the tubes. Failure to do so can damage the tubes. Instructions and tools for doing this are included in the manual/box (see photos). You will also need a cheap multimeter. This amp is very sensitive to voltage. I ran it on a VARIAC turned to right around 100V, and it never had a single problem or blown fuse. I strongly recommend you pick up a decent variac and give it less than 120V +/- for longer life and better sound. In addition to the stock tubes (which I put back into the amp for shipping), I found the best combo (to my ears) of rare and vintage tubes. Included in the auction are (all pictured): 4 Shuguang Treasure KT88-Z $129/pair2 Brimar 6SN7GTY KB/FE (CV1988) (13D2) (B65) Black Beauty Rare $5-600/pair2 RCA 6SN7GT Gray Glass Tube $2-300/pair2 Shuguang Golden Dragon 12AX7 Tube $200/pair The rare tubes will ship in a separate box in their original packaging and carefully padded and insured. Also included is a small DSD sabre DAC (https://www.spaceaudio.eu/old/) that can stream via USB, and some ultra-quality cables. There are resistors to cap unused inputs to reduce noise as well. (pictured) In addition to all this, there is a custom-made dust cover for the amp (pictured) It breaks my heart to let this go, but it only gets used a few times each year when I have company. Id like to see it go to a good home. Heavy and huge, will ship in two separate and fully insured boxes to arrive to you safe and sound. Shipping costs reflect this.________________________ Product Description: Features: User-selected amplifier modes, UT (Ultra linear) mode provides greater output power and TR (Triode) mode does smooth and rich sound. User-selected pure post-stage and integrated modes; Utilizes the audiophile capacitors and high quality metal precision resistors dedicated for audio frequency; Output transformers manufactured with Japanese silicon steel sheet and oxygen-free enameled copper and high quality lacquer, which offer a wide dynamic range at full rated output; Independent power supply for each channel.
