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"
