(The leveler) seems quite do-able, just a handful of resistors, a cap, and
a 6110.
You do not need the 6110 tube. While not totally unobtanium it may be
easier to replicate the sine wave leveler with the 190B leveler which uses
a pair of 1N97A germanium diodes and a different resistor network. It will
work equally well as the tube version used with the 190A. The TU-50 is a
combination of three production instruments housed in one large cabinet.
The three instruments are a 190 constant amplitude signal generator, a 180
time-mark generator, and a 105 square wave generator. Schematics available
on Tekwiki. - Ferrous
