    They both may be fine...or both might not. Info is sketchy on both. I will say that I bought a pair, as did many others here, of Tung Sol 6C8G black glass tubes from the India seller. Tubes were pristine and delivery was remarkably fast.
    Other than that, I'm guessing as much as you are. The $179 is a pretty good price on the ones from India. I'd write and ask about tube noise and microphonics and see what the seller says.

    Riddle me this...the Tele ECC801S has a very unique internal construction. If it IS a re-branded fake, what tube or manufacturer is it? Siemens?
  4. billerb1
    I'm guessing yes. Not that they are necessarily "fake"...but I've seen Siemens made/Telefunken label and Telefunken made/Siemens label.

    Put in for a full refund from Brent Jessee for the bad pair of Brimar ECC82 square getter, unless you have a tube tester you might want to think twice doing business with him, even with a tester I wouldn't personally buy anything again from him ever again. Just a heads up.

    Well I went REALLY cheap ($22) and bought a pair of 1953 GE ECC82 tall gray plates with large horseshoe shaped getters.
    I know most to all of you have said one time or another that this is not a preferred tube but I figured for what they asked for it, I’d give it a try. Does anyone like “any” GE’s at all?

    I believe @bcowen loves them, wait for him to chime in.

    Thanx, I will
    Just an FYI TK, I did pull the trigger on those late 1950’s (??) RCA Clear tops for $20 and a pair of 1957 RCA long black plate D getter ecc82.
    We’ll see how these turn out. I’m such a cheapskate as the Cleartops were $20 and the 57’s were $30.

    Yes, but if a tube has identical internal 3-mica construction to a legit Tele ECC801S, has a “raised” diamond between the pins and sounds awesome..BUT has a telefunken logo that won’t wipe off, is that tube fake?

    Asking for a friend. :D

    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. :wink:

    Actually, *all* GE labeled tubes aren't bad. Only the ones made by them. There were lots made by other manufacturers and OEM'd for GE, and those might be quite good. I have some GE labeled 7N7's that were made by Sylvania and they're awesome.

    So how to know if GE made a particular tube? Only way I know for sure is to plug it in and listen. If it sucks, GE made it. :slight_smile:

    To my ears the best sounding GE made tubes are the ones with the milky white getter flashing, sonic bliss!

    I picked up several of the Conn labeled RCA Cleartops that @TK16 linked a while back. Haven't had a chance to listen yet, but test wise all 6 of them are up there in CIFTE territory (meaning very high GM and near-perfect balance between the triodes). It's obvious that these were tested and selected by Conn or someone they contracted as 6 tubes at random wouldn't give readings that consistent.

    Yeah, and it's cool how the filament glows SO bright on those...for a half second or so. :slight_smile:

    That India eBay seller tests for a whole lot of things, Emissions, Gm, life, gain, shorts, gas, have you asked about noise/microphonics yet? Think I am going to pick up a pair from them.
