Do It Yourself (DIY) paradise for tube and SET project builders.

RE: Good point

I've got a fixed bias 2A3 on the bench at present . I have three pairs of 2A3 : RCA/Shuguang2A3C/Sovtek2A3 . All need more than 42mA to start singing , I use 48mA at present with 260V A-K with a 5k OPTX . May be worth bearing in mind once you've got it up and running to play with the op points a little
