I still use Winged C's for most purposes. But I am starting to switch to TS 6L6STR's for the 6L6 amps.

If anyone has a good "new" EL34 recommendation I am willing to test anything.

Hi Gary,

IIRC correctly you mentioned a while ago that you had "short bottle TS 6L6" getting noisy and even frying an OPT.
Were these TS 6L6 different from the 6L6STR's or did they improve the quality?

Best regards,

Markus

You are correct, I was having some issues a while back. But I tracked the issue to a vibration problem. Fixed that and have not had any issues since that time. Never blew an OPT, but they would get noisy.

The TS have a sweeter tone than the WC's. Now if can find a 12AX7 that I really like. Use JJ's now, but always looking for something better. The ones I have tried that are not my taste.... Reissue TungSols, Mullards (both GT and NS), EH, Sovtek and newer chinese. Does leave too much to try.

Great to know! Thanks a lot! :D
I still have a pair oF TS 6L6 STRs I got last year with a brown note kit. So far I didn't dare to use them. Will give em a try now.

Regarding 12AX7 I did a test a while ago with different tubes in a non-HRM position V2 (220k/150k).
I measured plate voltages of a bunch of NOS Holland ECC83 I got from a friend and also a variety of new production tubes (EH, JJ, TAD 7025). While all of the Philips measured similar plate voltages, almost all of the current production tubes measured between 10V and 20V higher than the Philips.
Only some of the TAD 7025 measured in about the same range as the Phillips.
Soundwise the Philips were clearly better than the new ones. Only some of the TAD 7025s came close. Since our sound tests usually involve some beers I can't tell you by heart whether the better sounding TAD 7025s were indeed the ones with lower plate voltages. :wink:

Do you think it would make sense (or did you maybe already try) to adjust the dropping string for new production 12ax7s to match the plate voltages of NOS tubes that sound nice?
I put this experiment on my to do list but since I'm happy with the Philips I never tried :wink:

Regards,

Markus

I use(d) winged C EL34's. It was from a "matched quad" but the tubes were all off by at least 12mA. Sound pretty good though.
Ive had surprisingly good results with shugaung EL34's and they measure closer than the winged C brand. Great tone for such cheap tubes.

Ive moved on to KT88's though, only tried Shugaung brand (again-cheap) but they sound nice and full and are currently my favorite tube type for D style amps. And ive pretty much given up on 6l6's not my thing, way too mushy in the bass IMO. To be fair ive only tried JJ's and Mesa branded 6L6's, and tungsol 5881's which sound nice but killed my clean headroom.
It's true i've lost my marbles and i cant remember where i put them
