Interestingly enough, a few months back, I repaired an old Metcal MX-500P
soldering iron power supply for our contract surface mount assembly person.
The old Metcals used 13.56Mhz at ~30W to power the iron heater. The whole
thing was really quite mechanically and electrically elegant, I actually
enjoyed digging into it and figuring out how it worked.
