Hey guys,
back from vacation and a fresh new set of EL34BHTs supposed to replace the set of KT77s residing in my Einy (100 W head) now, was waiting for me.
Last time I put the KT77 at 65mA per pair. I refreshed my memory at the tech corner of the site that the values for EL34s is in between 60 and 70 mA.

Any other/latest recommendations?

i usually biased my 34's between 32 & 35mA each tube (64 to 70mA per pair.)
 
Thanks Pauly !

I think about 30 mA each tube, 60 mA each pair is fine.

Don´t care about a few milliamps because main voltage
is not consistent.
 
Many thanks for the info. Put the tubes yesterday - I set it at 64-65. Works great.
These EL34 BHTs sound great. If you ask me Einstein just loves the EL34s.
