The EL84's seem to run abit on the hot side, but appart form that i havnt noticed anythign bad. I guess EL84's arnt the coldest runnign valves ever.

They are too hot to touch for any significant time, but thats about it. I think thats pretyt normal anyway?
Good morning Adibrook,
what g2 voltage do you run the EL84s? I expected something between 250V - 300V DC. Did you test the ECC81? (see #14 #15)
What kind of speaker are you using?
