Did you get those low on-resistance MOSFETs yet to cure the heat
problem?  IIRC, your original pair were getting hotter'n a
two-dollar pistol, and the replacements were expected to run
lukewarm.  Do they?

In the case of the propeller clock, I was wondering: why
complicate things by running AC through the slip rings?  Why not
rectify and filter the transformer first, then run the filtered
DC through the rings.  Easier to modulate than this
now-you-see-it-now-you-don't trick with the diode.
