Arte Forma Audio 805 S.E. Tube mono-block Power Amplifiers

PRICE REDUCED The premium tubes alone cost me $800.00 Up for sale is a pair of Arte Forma 805 S.E. mono-blocks. Excellent amps for high sensitivity speakers but also powerful enough to drive average sensitivity speakers, has 8ohm and 4ohm taps. I am including two sets of Psvane 805A-T and CV-181-TII tubes plus the original set. The original set has less than 100 hours use. One set of Psvane tubes are new, the other less than 500 hours use, estimated. I am the original owner, purchased new in May 2013. They look in new condition, I would rate them higher but I noticed when taking the pictures a tiny ding 4mm long 0.5 mm wide on the top plate of one amp. The ding is hard too see as its so small and didn't remove the black finish.
