The Growing Challenge of Buying NOS/NIB Tubes


An old forum post recommended The Tube Museum to source NOS/NIB tubes.  I noted it has Siemens Halske and Telefunken ECC802S tubes for sale on The Tube Museum website. I asked Mark for a matched pair of Telefunken ECC802S or Siemens Halske ECC802 tubes. He said he had a pair but the link he provided  were for Siemens E82CC and when I questioned whether they were true equivalents, this was his response:

You are incorrect.

These are TRUE AUTHENTIC TELEFUNKEN < > DIAMOND ECC802S.

Makes me think you are seeing the wrong pictures. Or, are ignorant about Telefunkn ECC802S tubes and their inner architecture.

E82CC Siemens are TOTALLY different - se he 2 meal tabs? See the < > between the glass.

You don’t know what you are talking about. Please, don’t insult my intelligence.

Needless to say, I was taken back by the tone and content of his response and the barrage of equally insulting emails that followed from Mark even though I told him I didn't want to hear from him anymore. SH ECC 802 tubes have a triple Mica and are not the same as standard E82CC Siemens or, in terms of quality, an Ulm Tele ECC802S. It gets weirder. The Tube Museum continues to show and offer for sale true SH and Tele ECC802, but when you try to order them, Mark tries to sell you something different and claims equivalency. When you question Mark, this is the response you get.

It's a further example of how hard it is to find reliable sources for genuine NOS/NIB tubes that are accurately described. I've had better results buying from European sources lately.

If you are willing to pay high prices for exotic tubes, then it behooves you to inform yourself regarding the features of those tubes that identify them with certainty.  In other words, caveat emptor.  The Romans had it right. For one example, even that characteristic diamond embossing on the bottom of every TFK 9-pin miniature triode has been counterfeited, and you ought to know how to identify the authentic diamond vs the fake one. This is not to say that the world is full of cheaters; sometimes the seller is also unwitting.

With the difficulties being met when opting for. Valves in a Circuit, and the risk can be to waste money. It is a encourager to look outside of a Valve Circuit and refamiliarise with SS Circuits.

I am at present having a SS Phon' produced along with a Pre Amp with a SS Circuit option. 

SS Power Amp's are also being home system trialled through 2026.

The secondary reason for the change towards circuit type, is resulting from a recent change of Speaker, the build up to the change has been long, with the idea of creating additional End Sound options growing in strength during the period of waiting for the Speakers.

The Speakers now in use have been so impressive, I am sure my own ideas coming to fruition will really add to the impressive End Sound experience being had. 

I had a very similar experience with The Tube Museum a couple of years ago with the same tube request (i.e. ordering one type of tube and getting a completely different set of tubes).  I have never dealt with that company again.  There are so many good tube providers in the market that do not disappoint, including The Tube Store, Tube Depot and Parts Connexion.
