Actually, the MHT series used a 6883B/8032A/8552 driving an 8643. The 6883B is the 12 volt equivalent of the 6146B and the 8643 is the next step "up" from the 5894. The HHT version had a 6883A/8032 driving a 5894. The 6883A is the 12 volt equivalent of the 6146A. The pin diameter on the plate connections of the 8643 is larger than those on the 5894.
The U63HHT had an output power of 80 watts, the U63MHT had an output power of 90 watts, and the U73 MHT had an output power of 110 watts. The power supply for both the MHT versions are identical. There is a jumper to change the high B+ between the 90 watt and 110 watt versions.

*actually a 6146 with 12v fil., which is a different # ...
