I'm sending my 1973 manufacture Superlead (1959) head cabinet to Sourmash to be restored. Somebody has seriously messed with this head cabinet previously. Despite the tolex being in REALLY good shape overall, it got spray painted off-white and lots of gold paint was used on the corner protector screws (it shouldn't even HAVE corner protectors, and these are oddball non-Marshall types anyway) and painted everything else brown that wasn't white. It has JCM800 style plastic spring loaded feet. I'm GUESSING that that's the wrong style foot for a '73 amp? Please confirm this for me if you can, and if you care to post a photo of correct feet for an amp made in 1973, that'd be helpful.
