Im trying to get a winter project going and i decided to build another RH84 amp but with 6v6. My question is, what needs to change on the rh schematic for 6v6?
At a minimum, you'll need to change the Cathode R on the output tube.
Maybe some optimization of the feedback R.

i do understand the bias need to be different between el84 and 6v6 but wasnt sure if there's anything else i need to know.
read the tubecad article on this subject and the classic Schade article. You may also want to look at Shoog's recent postings on the subject.

i would go for 250v for both the plate anode and the screen grid a very little bit under that.
it looks good on thd and you still get good watts also you can use the same opt
i think ?
