Sams didn't start until the 40's, I think(?)

I've been digging a bit, but it gets tedious.... I was hoping for a direct replacement, I should've known it would be a challenge. :-)

Apparently I've been to this site before.. I did download "Fundamental principles of Vibrator Power Supply Design" published by Mallory published march 1947.

Would be nice to find a book with the proper pin outs. I suppose I could peruse schematics and such. This one just has a retaining ring at the bottom, so I can open it up easy and I know that smell you refer to!

maybe I ought to work more on the contacts with my contact burnishing tool or try the 40 watt light bulb in series trick? it works but it speeds up and slows down a lot.

locating a vibrator is a pet project between radios for me.
