Hello,
Im new to the group. Has anyone built an amp. with or played with 5B
255M?. I have a load of these valves and would like to put them to
use. The curves seem the same as the 807/6L6 types. I would like to
know if anyone has had any experience with them before I go and build
something. I was thinking PPP class AB1 ultralinear.
Thanks Matt.
