    First pair of 1958 12AT7 TK1 Mitcham square getters and they're quite microphonic, more so in one than the other. Working with seller to resolve this issue. They do make quite the awesome sound though.

    Look like legit 1967s to me. Here's another one similar code and print:

    That perfect print that I can feel is a non issue? Both tubes I got have similar construction but the 1 with no paint has a bit fatter O ring, that makes it a bit earlier in years?

    BTW fellas these have no noise/microphonics on my MJ2. Those SN were not the U code on my single. You guys might be getting 67 not 70

    If it has the fat O-getter similar to the one that tube on the left has in this picture : https://www.audiocircle.com/image.php?id=82151 , then based on my empirical research should be earlier in years yeah.

    My last question bro is have you ever seen a 12AT7 variant tube with the straight and angled getter wire like the ECC801S.
     
  7. kolkoo
    I personally have never seen a tube with that construction on the net that's not a telefunken. Maybe somebody with more knowledge can chime in.

    Edit: I just found this https://jacmusic.com/nos/ECC81.htm and there is apparently according to them a Telefunken ECC801S made for Telefunken in the USA without a diamond? Interesting...

    Oh Schiit, so it`s may be possible, to laser cut some diamonds on this USA tube if it exists and sell them, hope not. Seen pics of GE make, they have much bigger getter flash and hard to see the getter. No U code either. Guessing they don't have the same distinct getter and getter wires?
    Found this but pics gone.

    Initial impressions 2 hours in are not good, can tell close to 100% if I am going to like a tube 2 hours or less time. As they are now they would not crack my top 22 list. Got 2 pair of Telefunken in that list. tilted towards the high end, recessed mids, muddy bass. Tubes did appear to look like NIB when I looked at them. Hope burn in helps. Maybe I`m just used to listening to warmer tubes and need to adjust. Did anybody else have this initial impression with those Indian Tele ECC801S?

    Tubes need at least a -2db at 10k to be listenable for me. AFO with the True-Fi profile was an awful combo with these tubes. Switched to the LCD2C which are quite heavy in my condition. I do think these are Tele tubes listening to them 4 hrs in. Going to have to redo my EQ setting for this tube.

    Just sold a pair of Mitcham and Blackburn ECC81 square getter, you should of asked here first. Not selling anything currently but others may have what you are looking for.

    That I know now... Bought these a while back. :slight_frown:

    Any thoughts on Telefunken ECC82/12AU7 smooth plate tubes? I don't own any TF's and am curious if these are worth a shot at less than $100 for a pair.

    Thx!!

    I wasn’t home to sign for the FedEx package today, so it will be tomorrow before I have my 801s in hand.

    Interesting story...I bought my second pair of 801s from Euroklang in Germany. Tubes arrived, both with permanent paint made to look smudged and one tube missing the diamond from the bottom. Same identical date code from 1970 on both tubes. When I contacted the seller, he was very apologetic and seemed like he really wanted me to return that pair. I didn’t because I wanted to keep them in my possession to figure out if they were real or not.

    So...I’m wondering if I have a real tele with no diamond that somehow passed thru QC, or do I have a pair of USA GE ECC801S that at least one got lasered?

    As far as I know, there are no other tubes with the same construction as the Tele ECC801s. That post referring to a rebadged US tube doesn't have a photo, so it doesn't mean it looked anything like a Tele ECC801s.

    There are plenty of fake ECC83, 82, and 81 around because the construction isn't so unique.

    Regarding the paint, it's likely that they're being reprinted to increase the value rather than the label being totally worn off, but are still genuine ECC801s.

    @TK16 the Tele ECC801s do sound a lot thinner than something like the Valvo 6201 PWs, which is why I ended up preferring the Valvo 6201s, but they do have the same separation and soundstage capabilities. Bear in mind that Bill's impressions will be different to ours as he has a Woo amp that also has power/rectifier tubes in the mix.

    Edit, the JASC music post is also referring to ECC802 and ECC803, which again, aren't unique in construction like the 801s. He only references genuine 801s being reprinted:

    "Telefunken ECC801S re-printed.

    This pair was offered for sale as NOS <> Telefunken. However it can be seen, the printing is not done with the silk screen print method as by Telefunken. It was stamped on instead with a rubber stamp and white paint. The numbers are not aligned nicely, so I assume it was done with such a stamp tool where you can plug in little rubber letters inside by hand. Moreover, the number "8" was put in there upside down, which makes it pretty obvious somebody did that by hand.

    It seems to me the tubes inside are real TFK, and it is not legal to repair the printing or the logo when it has come off. So no accusations here. I Just want to mention this here, that this is done sometimes, and sure some effort was made, because the Telefunken Logo must be ordered from a company who is specialised on stamps. Even so, this may have been done recently, but also 40 years ago. Logically nobody will make these costs of only one pair. So there must be many around of those. I just hope, nobody has the glorious idea to reprint <> 6211"

    The Telefunken ECC82 smooth plates are a fantastic tube, I highly recommend them.
