Possibly the Galaxy 2000+.  A full description was authored by Wilfred
Scherer, W2AEF and appears on p. 17 in the January, 1967 issue of CQ
Magazine.    A total of <gulp> ten (10) 6HF5 sweep tubes are used in
parallel.  The design also makes use of a dynamic linearizer by sampling
input and output RF voltage.  Non-linearity produces a voltage that's then
applied to a series regular in the bias supply.

Paul, W9AC

I vaguely remember the article and the tube load was 50 Ohms so there was no
Load control!!

WRL or Globe had a something 2000 that was all sweep tubes.
