According to a Lucas catalog, 78361 would be a 3 ohm heater control,
suitable for replacement of the original TR3 heater control (when combined
with the appropriate knob).

It didn't have 78392, but the TRF database has it cross-referenced to the
panel rheostat on 73-76 TR6.  (TRF puts the letters "LU" in front of Lucas
part numbers.)
