Threshold S500 CLASS A/AB STASIS W/OPTICAL BIAS MUSEUM CONDITION

I HAVE (2) THRESHOLD S500 CLASS A/AB STASIS W/OPTICAL BIAS SOLID STATE STEREO POWER AMPS IN MUSEUM CONDITION. I PURCHASED THESE FROM A COLLECTOR AND HAVE BEEN USING THEM AS MONO BLOCK AMPLIFIERS. THEY HAVE THE HI-FI TUNING FUSES, THE SUPREMES, WHICH RETAIL FOR $110.00 EACH FUSE, AND THERE ARE 5 FUSES PER AMPLIFIER. SO THERE IS $550.00 JUST IN FUSES PER AMPLIFIER. THEY SOUND UNBELIEVABLE. LIVE, REAL, THE INSTRUMENTS ARE IN THE ROOM. SMOOTH, BEST BASS OF ANY AMPLIFIER, WIDE OPEN MIDS, AND WIDE OPEN TOP END. JOHN THE PRICE IS $1800.00 EACH AMPLIFIER WITH " Y " INTERCONNECTS IF YOU PURCHASE BOTH ONLY. IT WILL BE PLUG AND PLAY. I WILL SELL THEM SEPARATELY BECAUSE THEY ARE STEREO AMPLIFIERS BUT WITH " Y " INTERCONNECTS AND USING THE 2 RED 5 WAY BINDING POSTS, I HAVE THEM MARKED WITH WHITE TAPE THEY CAN BE RUN AS TRUE MONO BLOCK AMPLIFIERS. NO SWITCHES OR ANY THING INTERNAL IS NEEDED TO RUN THEM IN DUAL MONO OPERATION. OR JUST PURCHASE ONE AS A STEREO AMPLIFIER. shipping $140.00 each amplifier to California and $100.00 each to the east coast.
