- The proposed mod should be fairly easy since the screen V can come
from a shunt zener-string regulator powered by the anode supply - dropped
through a R. This mod sounds good to me since AB1-grid-driven will solve
the 374's no tuned input problem.
- I would like to purchase the kaput tubes if you still have them. I do
autopsies and photograph the grid/cathode assembly if it's interesting.
(such as the 8874 photo in "Parasitics Revisited" in Sept., 1990 *QST*)
tnx. gud luck.
