Perhaps a leaky transistor. When was this built, and what are some of the transistor types?

It's a rebadged Metrawatt:

Here's the complete manual:

The cheesehead screws helped me close in on it. I have a Metrawatt Freq. Counter, Nixie type, all germanium inside, and good to a whopping 500Khz.

sprechen sie deutsch?? I might have a resource - a retired Navy Electronics Tech, born in Germany and fluent in electronics and German.

Cheers,

I kinda figured Simpson engineers weren't capable of designing such a beast, so different from their usual products.

I have an old HP counter that looks very much like that inside. But it works great, the 5245L I think. Silicon transistors.

Only having a block diagram is like navigating around LA with only a map of the freeways.

I thought the 405 was closed.....

PS - My German buddy at church is VERY interested in translating the manual, or at least the sections germane to calibration, and AC, obviously. I'll print it out and leave it for him - maybe he can get to it quickly. He's 70ish, and retired, but active with the food pantry, Boy Scouts, and other duties.

Cheers,
