Here are the schematics for the Collins
"Tubesters". I have several sets and have used these in
Collins S-line units for years. On rcv - the only downside is a
reduction in dynamic range when using
the solid state replacements.

I just did a quick Google search on 'tubestors'
and lo, there does not seem to be any info jumping right out at

they handled dropping the B+ down from tube range to FET range.
I have some lit "somewhere" but only like advertising, nothing
revelatory about the actual innards circuit. These didn't seem
to be on the market very long did they ? In Frank Zappa's
words, they were gone like the elephant's footprints in the
ocean.
