Hi Ryssen,
I think I have this figured out close,Anyone wish to jump in do so!
You got 2 channels so 2x6 transistors= 12 and 600va divided by 12= 41.666666 Lets call it 42VA to keep it simple per device,so if you use power rails at 42 vdc you can get close to 1 amp per transistor,half that to 21Vdc you could get close to 2 amps and so forth,it in actuality will be less due to losses,ect.if you read PAPA Nelson article on the BA-3 he states how to get more with different setups of source resistors,a good read ! I hope I have been helpful!

I will be trying many different configurations with this setup, including different caps, output transistors, and even thermal insulation. So as not to bog this thread, I will only reveal listening stuff here. To hear more about other permutations, check out this thread.

Humble Beginnings:D
As I couldn't wait to hear a BA3 with a F4, I decided to test it out on my F5. I ran the source through the B1 -> BA3 -> F5. And volia! I could hear music. And as Buzzforb described, the soundstage increase and the music is airy with good strong bass. I couldn't believe I could hear such a big difference. Thanks you Papa.

Default single endid bias

Has anyone tried adding a current source to one side of the follower output, Nelson talks about this in the "Leaving Class A" article? I'm thinking about giving this a try and wonder if anyone has any experience with it.

Thanks,
