Selling my entire system for upcoming move to smaller quarters in a different area. Sold my arrakis speakers so time to sell my amps and pre. The Siegfrieds are 2yrs old have approx 1142hrs on them and in perfect working order and cosmetic condition. They come with two sets of tubes. The recently added kt88 and original 6550 C. Both sets came directly from VTL and I have back ups of each. Each set has about 550hrs on them. These are in my estimation the best tube mono amps there are. They will be crated up in the original crates. All original accessories are included as well as the extra set of tubes. Pick up, best but can ship anywhere. Pay at pick up or wire transfer best option as well. paypal costs on buyer.
