Telefunken red tip

Brent Jesse has the best historical pedigree of tubes around on his site.
He's also a pleasure to talk to.

randy-11, not a trace of it having that sticker attached at one time. That’s what made me suspicious it might be a fake. (I’m a New England yankee, we’re suspicious of all great deals!) That and the fact that it looks TOO nice. I mean it is pristine. But, the internals appear to be identical to legitimate Tele’s, wiring, halo getter, etc...The diamond on the bottom to me looks to be raised and not laser etched, a sure sign of a fake. I can’t test it in my system for the foreseeable future due to a move and lack of a dedicated sound room for the time being. I think I will ask Brent Jesse if he would be so kind as to peruse a pic of it and give me his opinion...

put a magnifier on it and see if the red tip is paint or inside the glass

the stickers were used to mark Telefunky tubes as of select quality - red tips if real and never stickered could mean a lot of things...

OTOH, has tube manf. technology improved much since ALL Telefunky tubes were made?

and who would make better tubes than the Germans?

so if you don't have the Porsche of tubes, you probably have the the BMW of tubes

Brent is extremely knowledgeable and  a nice guy.   I have a few NOS tubes that were from him that I got in a trade.   High quality and geuine,  he is one of the best sources for NOS tubes out there.
