I was at the metal center at my local transfer station recently unloading some scraps that have accumulated over the winter when my nephew pointed at something hidden beneath a pile of siding and said, "What's that?"
I walked over to see the glint of a few neat rows of vacuum tubes. Of course I dove in and retrieved the item; an antiquated looking metal box with a p-2-p tube circuit inside of it.
The box itself is just shy of matching the size of a 9x11 piece of paper, five inches high, and is the painted old-school gray/blue color.
The box contains a @ 2" x 2" x 4" black painted power transformer, what is either a vibrator or large relay, a small-ish inductor, a black multi-cap, and:
1) A knob; you turn the knob and two plates get closer/further apart (with huge ground straps) It appears that there are maybe three large inductors with metal cores that move in and out? It appears so.
2) Four taps on the side labeled 'BAT' 'GND' V.C.' SFLD.' and 'D.L.'
3) 6X5, 6V6, 6SQ7, Can Inductor, 6SA7 (x2), multi-air core inductor, 6ck7.
Any guesses as to what this is? I may post pics later.
