Hope springs eternal for those who just stand and wait.....

Herewith the poop on the construction of the AC power unit of that flip-top Punysonic.

All the info that is needed:

Just a 12vac @ 1 amp power transformer and (4) 1N4000 series of
diodes to make up a FWB with or use a prebuilt bridge unit.

Also ,your all important info as to what pins the power comes into the unit as well as its polarity.

All of the DC filtering gets done within the sets electronics...just raw DC needed to be supplied.

Fuse values and expected current values also provided.

The only odd part being that custom molded power plug that is used on the unit, at the minumum you
might use some octal tube pins slightly compressed to size, with multiple heat shrinks for insulation.

Plus keeping a close eye on the polarity when installing.... with a warning put on the unit.
Or possibly get REAL creative with a replication of the plug made with Bondo or fiberglass epoxy boat resin, and mold up a plug unit and its 2 connector pins to later be installed inside after the cure.
