I did find a 6H1 tube. See http://www.mif.pg.gda.pl/cgi-bin/vs4.pl
any clues? on mystery TOOBS...
I found a Quad of Tubes! no markings other than 6H1C ? no brand name on them? diamond logo, or stamp w/the #30
inside of it...or the other marking is a big circle with the (6H1C) inside of it. So can you help a brother out, and tell me what these are?
thanks in advance
Craig
