This is an early 2007 (still made here in US) WT-800 C, which is the latest and most current revision of this amp. Chances are, if you're checking this out, you already know about this amp and maybe have been an Eden owner before, like I was. It's a great amp! And, this one is in very good condition: -Has been biased by Solid Amp Repair in West Seattle within last 6 months -New 12AX7 tube -Added tube shield, non-stock -Added new power switch from Eden -Went through the insides and completely shielded and grounded all the signal carrying wire runs! Greatly improves signal to noise ratio. -Amp comes with rack ears -Very, very good physical condition - especially impressive considering the amp's almost 6 years old -The WT stands for World Tour - can be configured for any voltage around the world -26 lbs, 1100 watts into 4 ohms bridged! Much more watt per weight ratio compared to an SVT or similar amp -Two internal power amps, can be run in stereo (2x550 watts at 2 ohms, 2 ohm stable on each side), biamp with adjustable crossover freq., or bridged mono (as said, 1100w 4 ohm, 800 or 850 into 8 ohms I believe) -This revision of the amp can be used with 4 ohm loads in bridged mode - the older A and B revisions could not be. $750, shipped to your door! If you have questions, please let me know! No trades, with the only exception being fEARful bass speaker cabinets being a possibility (possibly plus cash), thank you.
