Um, I think your 1B3 in your picture is redplating...

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!

OK, I wasn't sure, I've only seen that happen in real life to some old 7027-A tubes in an old Stromberg-Carlson Stereo Amplifier from the late 1950s, and more recently my 22" Zenith TV's picture tube, and I never realized that was a sign of a gassy tube, especially on the old 7027-A tubes that I had in an old Stromberg-Carlson Stereo Amplifier I used to have years ago.
