I built a 6AH4 preamp for someone else and
found they like at least 20mA to open up.
I used 2 D NiCad on the cathode and
100V on the plate choke with cap coupling.
Worked out to 80Vpk and 30mA operating point.
Sound was like a 6SN7 with a 6BL7 drive.
Clean like a 12B4 but richer and better layered.
