Joe, I've one (Hickcock 752) also. A while back I did have to replace my
#83 tube, but I always wanted to know if there was a practicable way to
solid state that circuit and regulate it accordingly to the testers's
spec maintaining tube testing accracy. Seems as if therehas to be a
good way to accomplishthat, maybe something someone else as already done.
