Yaqin CD1 Tube Buffer

This is the SINGLE tube model that uses the 6922 Triode tube..Purchased from Pacific Valve & Ece.2 years ago...It was installed between a DVD/P & surround receiver for stereo listening but I moved shortly after buying it & it has set in it's factory box for the last year & a half...The unit is BARELY broken in with around 200 hours use..I just pluged it in & it fired right up...Still sounds wonderful(on modest system)...The more modest your system the more benefit you will gain from this unit..Has an upgraded JJ Tesla 6922 & the factory tube which has NEVER been used...The unit is in EXCELLENT condition & is graded 7 just to be safe,the facia is scratch free!There is a small scratch down one side of the transformer(see pic)but it's barely noticeable...Check all the reviews,this is a budget KING,with the ability to transform a modest system!Price INCLUDES PayPal & Shipping...Thanks very much...
