When I first purchased the amp the seller said it was a 1962.  The the gold Oxford speakers are dated '62.   Since I decided to sell it, my tech gave it a tune up, it had to be capped. We matched a quad set of black plate RCA tubes, set the bias, and everything else checked out OK .  The original transformer dated '63 the chassis dated '63.. The grill cloth has been replaced ( I still have the original if you want it. It has 3 small holes) The dog bone handle is a replacement ( I have the original also if you want it. Its broken as most are.) 

The price for shipping is USA only.
