Thoughts on this little oddity, anyone ...?

His " Magnetic Field " amps were nothing of the kind. They simply
employed
a triac based voltage regulator in the AC supply to improve the
regulation
factor of a ridiculously small iron transformer.
Hmm, was anybody in the 70s not obsessed with triac pre-regulation in all
sorts of power supplies?

Want some?
As I said, all sorts of old power supplies were made with SCRs and
preregulators before the transformer.
The smaller HP/Agilent bench power supplies are still made this way. I
guess you get a smaller heatsink and a little more efficiency.
