Dave,

ISTR the Gates BC-5H and BC-10H were fully transistorized except for modulators
and finals just like the MW-5 and MW-10. The difference was they were plain
old high level plate modulation also like the MW-5 and MW-10 and, naturally,
had a pair of modualtors (3CX3000's IIRC) and a pair of finals because two
were less expensive than one (believe these were 3F2500's). ISTR that the
"H" designation meant "hybrid" IOW tubes with solid state drivers.

However, you are right in saying neither the 10H nor MW-10 can claim the
first 2 tube title although the only tubes were PA and mod. output. :)
