I guess Filament bias with combination R and Sic makes better sense.

Quite possible. I haven't looked up all the data on heatsinking, if there is any. Can anyone give me ballpark figures for these SIC devices?

Well, these diodes usually drop about 1V. Multiplying by the current in question is the heat that needs to be considered. Example: (01a) 1V x 0.25A = 0.25W per Diode to be considered.

All the best,
Ulrich
