    I'm not sure.
    Yeah, I agree, this is valuable info. I think a more appropriate place for it would be in Marty's tube thread, but it'll get buried, so sticky'd it is.

    My '87 2210 had the same (I believe) tube, but with red 12ax7A printed on them the same way....I compared the pic to one and everything looks identical...I was told by sccloser on my post that they were Chinese...they don't sound too bad.....I put a couple of Groove Tube Golds in for now and the tone did get a little tighter and chunky.....I have a pic on my thread [​IMG] Original Tesla EL34....? it's not too clear of a pic, but on my original post it's the 3rd tube.....wow,I can't believe I actually helped someone with a tube question.....the getter, the plate, and everything looks the same as mine...I have five of them.....I'll stand corrected of course....

    thanks for the info 61rocker :)
    yeah i compared them to a new Shuguang and the plate setup looks the same.
    my ECC83's sound much better than the new 12ax7a and 12ax7b's but all
    are noisy and suck for getting clean tones. good Metallica type tone though.

    Shuguang 12AX7-A

    Penta, Ruby Tubes, and Groove Tubes use Shuguang tubes.

    Thats really useful information, filed for future reference, thanks!

    Do you know which amps the Shuguang tubes are used in these days?

    you mean preamp tubes? pretty much in every amp i guess....usually they put JJ's in V1, because the quality of the low microphony tubes is more consistent, but the for other stages they use both brands

    I have the 000-10 EL34's in my new JVM205H, which is listed as Svetlana. Others have said these are SED =C= ?? We know SED used to be called Svetlana, and are made in that factory, but the "new" Svetlana is New Sensor - anybody care to elaborate as to which tubes are in the JVM??

    rest assured they are winged C's
    svetlana is still svetlana in europe although they do have the =C= logo
    svetlana is no longer allowed to carry their own name in the US
