Isn't that the 1 that tests minimum?

Yeah. So? What you need all those extra mho's for anyway?

 

[jb77]

Here's one for $80 with free shipping. Is that a good price?

I must have unintentionally cut that part off.

ROFLMAO!

Maybe I should rephrase.

It’s well known that authentic Telefunken tubes from the 60’s have chalky paint that can be wiped off from light handling. Did Telefunken improve the paint in the 70’s? I’m pretty sure the ECC801S is a 70’s era tube. Anyone know?

Thanks, I will hang up and listen.

I believe the chalky print stuff to be bull. That's my own personal opinion I've formed when owning a ton of tubes (not just Teles), some with chalky print, some not, the chalky print for Teles can be used to discern if at all anything - the date, but the construction tells us more anyway:

ECC801S Teles:

1) (circa 1956) Oldest type - double fat getter, the mica is not-transparent, the rods are nickel/silver looking, 1 plate hole
2) (circa 1957-1958) A bit less old than 1) - single fat getter, the mica is not-transparent, the rods are nickel/silver looking, 1 plate hole
3) (circa 1958-1959) A bit less old than 2) - single fat getter, the mica is transparent, rods are nickel/silver looking, 1 plate hole
4) (circa 1960+) A bit less old than 3) - single fat getter, the mica is transparent, rods are copper looking, 2 plate holes
5) (circa 1960+) A bit less old than 4) - single thin getter, the mica is transparent, rods are copper looking, 2 plate holes

@bcowen is trying to get back at me for revealing his true love for all GE made tubes, not the GE labeled that are made from other factories.

That's the info that I was looking for, my friend! I have a pair in category 5, with thin getters. Date codes on both are U7010206t, which I believe is 1970. 4th number is year, correct?

According to the chap in India, I have a pair with '66 and '70 dates incoming. I will compare the getters when they arrive this week.

As to the print, what bothers me is that the paint is made to look slightly worn-off, but it is permanent paint. No amount of rubbing removes it.

What doesn't bother me is how spectacular these ECC801s sound on my rig.

Mine look like 1970, 4th number in the U code is the year, other letters signify month. Others decifer the rest, sure some hear can explain them or link you to it.

 

[OldSkool]

TK, almost ALL of the TFK ECC801S I have seen for sale have zero in the year code. That coincidence also makes me suspicious.

I hope I am wrong.

U code looks like 7 numbers in the pic ad, and the SN are 6 numbers in the pair descriptions. If the pic in the ad is the same tubes as the box SN, the U code is a completely different number. My pair is due Thursday, will know for sure then.

 

[OldSkool]

Thursday as well on my pair. Read the description in this expired sale ad. Are we actually listening to a GE tube reprinted (with diamond lasered) to look like a Tellie?

[TK16]

Wish I could see what the getter looks like on those GE, but they don't have a diamond or U code. Ivan should be able tell if these are Telefunken ECC801S, imo they are. Do you see any similar 3x mica with those 2 getter wires made by another company? Imo these are Telefunken ECC801S, but I'm no expert.

My question was just answered by the seller, and he said "it has the U code" when asking about the SN. Mine are 1970 vintage. He might of gotten a sealed box of 1970 tubes.

 

[OldSkool]

I have been searching for pics of every 12AT7 or 6201 that might also have the top translucent mica and double getter wires, but no positive ID yet. The Siemens all have the 4 seams on the glass top, so no match there.

I hope they are legit, but if not...lets figure out what they are and chase those with out paying TFK prices.

Very nice link showing and explaining fakes, including Telefunken.

Been doing some comparison between a high testing VG0 1959 Hamburg PW, a very high testing pair of 61 DF "something" Hamburg PW, and a high testing VG0 Hamburg 59 PW with a lower testing tube VG0 Hamburg. The 59`s have a good amount of weight and rich creamy tone (almost Heerlen CCa PW) over the 61`s. I could not tell any difference between the 2 pair of 59`s. All 3 pairs shared the same attributes that make the 6201 PW Hamburg`s magical sounding (other than the differences noted above).
