hello!
I want to build a good 30w class A or AB1 triode amplifier.
this means I have to go for PP operation, sins i dont want to mess with 1Kv...
another thing is that from my experience (which is very limited..) I prefer the older tubes (30's 40s') which brings manly 300B or 2A3..
I never used one of them, but i have a filling that i will prefer the 2A3 and from the places that i know it is cheaper to by 8*2A3 than 4*300B..
now i have a few questions;
is anyone have any experience whis PPP 2A3?
what should i go for, fixed bias or self bias? (I think I prefer self bias..)
what operation point do you suggest for the 2A3?
