I was gonna say i still use some Siemens 34s in my Plexi I pulled out of my old 100B.Originally posted by SQUAREHEAD
When Reinhold forst started production of the Xtcy, he ALWAYS used Siemens 34's... for the first few years, until he could no longer get a good supply. They all (Ecstacys) run around the 500 mark. I've always used them in my Xtcy's and NEVER once had any problems.

I love 'em. Sheet...the ones in my plexi have been in that amp since about 5 years...and had already been in the 100B 2 years prior.Originally posted by SQUAREHEAD
Yep!!
Great tubes, Ed!!
I've never had one die in 20 years of using them in about everything I've ever owned.

What's with all the warnings anyway?
They seem fine in any amp I've ever used them in...![]()

I'm assuming that you haven't tried more than a handful of these tubes in your various amps. It's always possible to get lucky. Some tubes will beat the odds.
Even if only 10 to 20% (which would be optimistic) would fail in amps with plate voltage over 450V, it would be pretty lame to recommend them for such applications knowing this fact.

Hi Mike
Thanks for the reply. What do you recommend for the EL 34 Shiva?

SEDs, GT 6CA7GEs or Mullards (which are VERY pricey).

I've seen Seimens run forever at real high voltages and I've also seen three of them blow within a couple minutes at around 500 volts from personal experience. If they are gonna go they will go pretty quick. Bogner may be running 150k bias resistors between the PI and out put tubes or may have a high value screen resistors in his amps, both of which will help. They are nice sounding tubes but Mike K. is right about them.
