The US mains transformer was not original so we installed a good quality (Hammond) replacement which runs at UK voltage. The output transformer in there when I acquired it is also a good quality modern replacement (Mercury). I replaced the chipboard baffle which Fedex had kicked to pieces with a nice pine ply. The Eminence speaker was sounding horrible so I installed a nice Weber Alnico Sig8A-S. Also installed a new 6V6 as the existing one was playing up. This amp is now looking and sounding very lovely again. It's not a collector but it is electronically and physicaly sound and will last another 50 years without breaking a sweat. It's a drip edge, so hand-wired blackface circuit, much, much better amp than the current crop of reissues.
