And a pair of 4-125 in push pull to modulate the 4-250.

Probably 2-30 MHz.

It also had a built-in VFO (I think they called it a "MO" master 
oscillator), which was a Collins type (perhaps Collins manufactured) PTO.

There was also an amplifier often paired with the T-368 (and perhaps 
earlier with the BC-610) which used a pair of 833s in push pull, with 
plug-in tank coils, not band switched. (maybe it had a band switched 
input circuit, but not the output) The MARS station I hung around had 
these. I wonder if anyone following this thread happens to know what 
that piece of equipment was called?

At the MARS station they used R-390s and T-368 for RTTY service. I don't 
know if the pair of 833 could be operated as a linear amp, with the 
T-368 in AM, or if it could only be used for CW and FSK.

As far as I know at that MARS station the only fone ops were done with a 
KWM2A and 30S1. The T-368 were used exclusively for RTTY.
