Looking to move on to another amp for my HD800's. Amp was bought on 2/20/13. I have three sets of tubes: 1. AMPEREX 6DJ8 ECC88 ORANGE LABEL VACUUM TUBE MATCHED PAIR 1974 CHECKED TEKTRONIX ($70/pair) 2. AMPEREX BUGLE BOY 6DJ8 ECC88 VACUUM TUBE 1964 O GETTER STRAIGHT MAN MATCH PAIR ($90/pair) 3. Stock GE tubes Also have socket savers from Tubemonger ($50) Amp is in great/perfect condition (9.5/10). Can include PYST cables if needed. Or just the amp w/stock tubes - $385 Paypal only (not included). Shipment can be worked out.
