    I'd avoid anything other than SED's in a Bad Cat. Bad Cat runs the tubes beyond spec (which is pretty wacky) and some EL34s can't handle that (in reality, none should).

    The SED's do. Other New Sensor (the company that makes Tung Sol Reissues and others) offerings don't do well under undue stress so it would be hard to recommend the Tung Sol (reissue) without a long positive history which isn't available yet.

    Mike Mathews (new sensor, sovtek, etc.) bought the rights to the name "Tung Sol" {and Mullard, and Svetlana, etc.}.

    So now he can legally (if not ethically, IMO) print "Tung Sol" {or Mullard, or Svetlana, etc.} on just about anything he wants to.

    Does doing so make them "bad tubes"? Nope.

    Does doing so cause confusion? I vote "yes". I have no idea what I'm getting when I buy tubes labeled Sov / EH / Tung / Mull / Svet

    Best advice: Try them. If you like the tone, there ya go! If they last, better still!

    mn

    EDIT.....I was writing my thoughts while Mike was posting. I'm an "amp guy", but I defer to Mike on "all things tubes". If he says "not recommended", that's good enough for me. FWIW

    All I'm saying is that the jury is out. There's no data to confirm that these are good under normal conditions let alone under Bad Cat "let's exceed the maximum spec by 40% just for the hell of it" conditions.

    Yes and yes. A quick visit to my website will certainly illuminate :AOK

    The funny thing is Tungsol never made EL34s.

    My Hot Cat came with matched Ruby's in it if that helps.

    Have you looked at New Sensor Tungsol EL34 labeled tubes vs. New Sensor Mullard EL34 labeled tubes? Are they the same or is there some characteristic of Tungsol that they are using in the Tungsol version?

    My guess is that they have several names for each of their tubes.

    I also suspect that if "factory A" can't keep up with "mullard 34's" there's no qualms at all about labeling "mullard 34" onto tubes from "factory B"

    Since there never were Tung Sol EL34s this would be impossible.

    Don't know what the voltage on the "CAT" is but I've been installing JJ E34L's from Eurotubes for several years now in Music Man Amps. Plate voltage is around 700v. NO problems yet other than a rattley tube after a couple of years. Not ONE failure. A lot more than I can say for GT's and Sov-bombs. BIAS_BIAS_BIAS! Mike.

    Many of the EL34s GT sells ARE JJ's.
