One of my favorite RTTY pieces - - -the Northern 105 (numerous models) with matching power supply. It a great converter with variable shift and a 2E26 final that can drive anything or you can run it barefoot running a few watts.
Its easy to drive the T-195 as the transmitter  all ready has IN/OUT BNC connectors for the VMO.
Tons of Northern equipment came through MARS years ago and tons of Northern equipment  sadly went to the salvage yard.
