: A lot of The Radio Amateur's Handbooks of the '50s and '60s had 892B

: has "A 100-Watt RF Amplifier for 50 and 144 Mc." on page 405. It runs
: push-pull class-C, up to 120 Watts CW or FM, and 100 Watts AM.

Gone by the 1955 edition I have. The 1947 ed uses it in 3 2M TX circuits.

I have 3 RCA 829B and 6 or 7 slightly sturdier UK mil CV2666 equivalents,
plus some CV178A / 5894 bottles I intend to use sometime in something:-)

There used to be a *relatively* popular surplus rig that used three of
them. I remember they were lined up and as I recall the final had a
tuned line output link coupled to the antenna.

Don't remember what it was called. That was nigh onto 40 years ago.
