I have old commercial 12bh4a linestage and it kind of sucks so I plan to hack it with VR tubes , CCs and put a BAS choke on the plate. That ought to cure it :)

The 12B4 is pretty hard to screw up... :) Don't forget its relative, the 12A4 either...the mu is higher.

  Well, it's all debatable. If you ask $16k for a 12bh4a linestage it needs to be little better than plain Jane 12bh4a, and plain Jane 12bh4a is nothing to write about.

    You do have a point. I never worry about such things...I just go and build something I think interesting. If I had to worry about an expensive component, I doubt I would get very far...LOL

I use CCS feeding VR tubes at the ouput of my power supplies (preamp and driver stage supplies) - Tre' 10:54:28 05/07/24 (0)
