EL34EH Vs. EL34JJ

[Tiago]

Hi all,
After some digging and googling around couldn't find any decent information about these tubes.
I'm just about to buy a pair of EL34's for a Dynacord Eminent (schematic attached), and I want to know the opinion's of the "ampagers" (remember that old forum, text and frames that we all loved?! ;)) about this tubes.

Regards,
Tiago

I would use EH, because a friend of mine was very shocked when his JJs burned away in a Eminent 2T...

It seems, that the operation point of JJs is slightly unstable.

Thank you very much.
Now definitely will go with the EHs. There was one other person that told me bad things (reliability issues) about JJ EL34's some time ago, but at first I tought it was an isolated case cause JJ used to have a good reputation.
Now I know...
Thank you!

Or spring for the "good stuff" and get some NOS Teslas.....

"Winged C" EL34s are nice as well.
