As you can see from the box, shipped direct from Manley labs on July 2017. I bought it with out stock tubes. All tubes are upgraded and included, Quad matched Genelex Gold Lion PX300B, Tung-sol match 6SN7 and 6SL7, Tung-sol 5AR4 rectifiers. Upgraded main fuse and B+ fuse to HI-FI Supreme tuning fuses. Comes with all the original accessories and box. Like new condition. Shipping to 48 lower states only.
Vacuum Tubes: 2 x 300B (Output), 1 x 6SN7 (Driver), 1 x 6SL7 (Input),
2 x 5AR4 (Rectifier). (Units prior to 2011 used 5U4 rectifier tubes.)
