Upcoming major winter restoration project:
Hammarlund Super Pro SP-400-X, in amazingly good condition, especially considering that it is about 65 years old!.
Got it in exchange for fifty "AA5" NOS and used / tested tubes, from an old-timey radio repairman. He had no real interest in the radio, he thought it was a "ham transmitter" but wasn't sure.
BTW the 50 tubes I traded for it were mostly from the "plinker pile" and cost me nothing, except for some effort...
I'd been looking for one of these babies for, oh, about the last 40 years...
Tomorrow I go see the doctor, to get my back disks and hernias checked out ;)
And, next week, he is supposed to bring me its separate power supply, just has to ecavete his storage building a bit deeper.
After that, a careful inspection, check all the paper and electrolytic caps, look for out of spec resistors, etc, long before actually applying AC line voltage...
