Mastersound AYON 300B

For your consideration I have a Mastersound made Ayon branded 300B integrated amp for sale. Amplifier comes with Vaic 300B-XLS, Sylvania JAN 5687 and Sovtek 12AU7 tubes. I can upgrade the small signal tubes for an extra charge, although this sounds great as it sits. This unit has been sitting in its original crate in a heated warehouse for over 10 years! This was, at worst, a show demo and at best it has never been used. This has very very few hours and perhaps none prior to my testing. All tubes tested as new and the bias pots sit at exactly (or extremely similar) position.
A manual bias amp, the bias pigtail will be included but it should be noted that bias has held stable for the entire time I have been using this amp. I have another of these amps in slightly rougher condition that I may sell but at this time I am keeping the rougher/older unit. I cant say enough about this "hotter" 300B tube. More dynamic, more linear with greater extension at both extremes than traditional 300B tubes. This variant is still made by KR and EML. I read that this is a 20,000 hour tube, but take this as you wish as so much of tube life depends upon use and the amp in which the tube is used. Suffice it to say that I greatly prefer this tube to the regular 300B. 
This has 4 inputs (direct, aux, CD and tuner). No phono stage. The direct input is for the use with a preamp in which case this is only used as an amplifier. No remote is included but a copy of the owners manual will be sent with the amplifier as will the original shipping crate which was sent from Vincenza, Italy to Austria (Ayon) and then the U.S. directly to the, then, importer of Mastersound products. 
This is a 20W/ch, 40W/ch peak output, single ended pure class A amp with 0 negative feedback. Shipping weight of 100 lbs, unit weighs 68 lbs. 11" (w) X 21 1/4" (d) X 10.5" (h). The current version of this amp sells for over $ 6,500.00!  The black wood side panels (perhaps a veneer) look excellent as does the back. The only larger imperfection (on surface) in the chrome is in the photo showing the large middle chimney in the back of the unit. There are minor imperfections in a few areas of the chrome that look more to be due to age than use. The key issue I think is the fact that there is no sign of useage but rather any issues of condition are simply related to the condition of the chrome which is age related.
Price includes any Paypal fees with shipping cost extra. Extremely well built and with superb sound; I think the buyer of this amp is in for a real treat.
