This was purchased brand new from a licensed dealer (Spearit Sound) less than 6 months ago. It is in absolutely perfect condition. It includes the following extra NOS tubes: RCA black plate 12AX7, Tungsol 12AX7 and a matched pair of RCA black plate 12AT7 along with the stock tubes. The extra tubes were bought from ultra reliable tube dealers and I guarantee them. I went on a tube amp spree several months ago and listen primarily to a 6V6 amp now, so I suppose I should whittle down the "collection". Also selling a Cayin A-50T, see my other ad. The asking price is very fair but negotiable. I prefer paypal but all listed options are OK.
