Question Real Telefunken E88CC?

Hi All:

I just bought a Telefunken E88CC from a big online store. It has yellowish/pale white markings instead of usual white that Telefunken use. It has a diamond on the bottom. The box looks new and crisp. The marking paint does not get smeared if I rub the marking with cotton shirt. The date code is U3218104.

Please help me decide if it is a genuine Telefunken E88CC? The solid pale paint is making me suspicious.

Thanks!

I have got a few 100% original Telefunken E88CC here. They look very much like yours.
Differences being:
The printing is white on mine and the word "MADE" is clearer. Yours looks a bit like "MABE"
You can find some very nice pictures of the Tele E88CC on:

Before posting here, I actually checked your website and many others. This also lead me to believe something fishy about this tube. Although the tube looks like very much like a Telefunken but I have never seen such glowing golden pins in a NOS tube before. Then the off-white (pale) markings on this tube are made by very durable/hard paint and they cannot be disturbed even by cotton rub. While Telefunken marking were infamously fragile. The tube box is also very crisp for something packed 45 years ago, i.e. date code on the tube suggest 1968 production. I just returned the tube!

Nonetheless I still want to hear members' opinion.

Just to make things clear: it is not my website.
My E88CCs are used pulls from VHF equipment of the 1970s.
Their pins are gold plated but not quite as shiny as yours, maybe just dirt.
The printing on my tubes is chalky, very easy to wipe off. As usual for TFKs.
Did you bother to translate the captions of Jogi´s photos? In of them he tells of a find of some E88CC made by TFK in West Germany, one even with a West German army marking in the form of an eagle. What is interesting is, that these tubes were found in an East German (GDR) radio surveillance van. Some cold war thing where they received all kinds of wireless communication from the west.
Here in Germany you get to see a lot of TFK tubes with that wipe off printing in chalk white, and also a lot of GDR made tubes that have yellow(ish) printing in rugged paint. And now you are showing a tube that seems to have TFK technology and GDR-like printing.

If these are pulls from 170s equipment, they are almost certainly genuine (assuming they were there since the equipment was made, which is not actually a bad assumption). The fakery strated many years after that...

In principle with a true gold plating there is nothing suspicious if the valve has never been out of the box and stored reasonably well. Gold doesn't rust or tarnish in normal conditions. Once it is plugged in one can remove some plating and then it will start to get some oxidation from the underlying metal.

About the printing and the doubt about the originality I agree.
I don't have TFK E88CC's but have some NOS/NIB ECL80's (without diamond) and other used true TFK's whose chalky white printing is really weak and easy to remove just rubbing gently with a finger.
In general with popular valves like ECC88, ECC83, KT88 etc. I think one has to be very careful because there are Chinese replicas around. As these are very popular with a potentially good market they have been made.
This hasn't happened with less popular valves or older types until now (in my knowledge).....
You can find a "true TFK" E88CC in the old Tesla E88CC that is still available. The last ones were made in the 1980's I think. Also here one has to be careful because the first JJ's where still branded Tesla but they were not the same although just as good for the most important features. Here it is easy to distinguish as differences in the glass shape and other visible details are quite striking.

Hello,

I can't see from your photos is it straight or angle getter arm version? According to code they should be angle getter arm!

Did you try to test them?

Many suspicious Telefunken E88CC appear last few years.


I've got these E88CC 6922 Telefunken more than 20 years ago, before any dirty tube business started.

These E88CC Telefunken I've got 6-7 years ago.

Both versions are original Telefunken's, first version I have in qty 100+ and it's amazing how they are almost equal in all parameters on tester, the 2nd version too.

The diamond molded in the bottom of the tube indicates it's a real Telefunken. It may have been re-lettered, and whether it is an E88CC or not isn't clear. But it is a Telefunken made tube.

It's a genuine Telefunken tube but very likely re-marked and with freshly (gold) re-plated pins. Might be a close (cheaper) variant of the E88CC like the ECC88 or PCC88 or any B9A dual triode with vaguely similar characteristics. The "too crisp" looking box is also suspect. Obviously a "re-worked" tube and you made the good decision in returning it to the seller.
