Those HV Rectifier tubes aren't supposed to glow purple like that, the only tubes that should glow like that are your gas discharge regulator tubes like your 0A2 and OA3 tubes for example.

no, it was just VERY old, and as gassy as a grandpa after a bean festival!

oddly enough, the old one had no flashed getter , where the new one did.
I still have the bad tube just for fun!
