[Amps] Bad tubes from Ebay

[Peter Voelpel]

Hi Larry,

The seller who sold you the GU74 is a very bad example.
I also had problems with him.
Good experience is with "qro-stuff" and "alex550-2".
>From both I bought many items, mainly GS-35b tubes, vacuum variables and
vacuum switches, all items new in their original boxes.
I was always very happy with that stuff.

Personnaly I have no experience with GU74 tubes from those sources.
Friends mention that you need at least ten tubes to sort out a pair with
identical characteristics, they vary extremely.

Recent purchases of russian tubes from Ebay sellers have been pretty
disappointing with more than 50% DOA's. A summary of my experience is at:

And yes, I did try to "condition" them first but it's hard to fix mechanical
shorts!

As for me, I will no longer buy tubes from non-US sources.
