Can anyone identify this for me? I don't know whether it is a fake or an odd model. Thanks!

Any tube produced in the Telefunken factory should have a "diamond" molded into the glass in the base of the tube inside the circle of pins.  If you don't see this diamond,  then the tube wasn't produced by Telefunken. Fakes have very nice writing and the printing will not rub off with your fingers or water.  So if the tubes you see have really indelible printing, suspect that they are fakes.

The 60100 code doesn't ring a bell. normally its letters and numbers for the date codes, no idea about that

Cripes - I've been outbid three times - I guess there's no way to get the awesome deals y'all got anymore - the word must be out on this amp.

That Ultrainferno has apparently been reading and reading and reading! The only thing I could possibly add is it could be from the former East Germany or from a little farther east... The question is, though, "How does it sound?"

Look for auctions ending mid-week and be patient. Don't bid until the last 10-15 secs and bid the max you'll pay. Try Gixen to snipe on auctions you can't cover in person. Oh, and I'd try to snipe a Indeed G2 over a Bravo V2. It is a better amp for a bit more green.

I have been reading a lot about tubes yes, well mostly only about the ECC82 and equivalents but you were the one that got me going.
I still owe you a beer for that, remember? I suggest we go to the Octoberfest 2011. Headfi meet

 
What i've read is that the fake Telefunken sound horrible, but I can't tell if this is a fake or not
I've stopped buying 12AU7 tubes as I'm not using that amp anymore...

I shall test it out tonight and see how it sounds compared to my other tubes. It maybe interesting.
 
I suspect that it is not a fake but made in the eastern part of Germany. I don't think anyone would put a fake tube in that kind of old junks anyway.

 

[Ultrainferno]

What old junk was it in?

Telefunken tubes from east Germany have no "diamond" mark between the pins and I've read they don't sound great.

Just placed it into my Bravo V2, set the bias at 12.8V on each channel. Actually it does not sound bad at all. Background is low, high sounds on par with my other Sylvania grey. Possible the sound stage is not as wide as the Siemens and the Sylvania, but all sounds pretty good to me. I really need to try it out later on this weekend, I am so bloody tired today......

 

[Ultrainferno]

How do you set the bias on a V2??

Oh, I've actually done some of the mods, so the 3k resistors are now replaced with 5k trim pots.

 

[Ultrainferno]

Cool! Pictures!

 

[swbf2cheater]

so nobody knows where to get a power supply for them?

Very carefully!
