I need a schematic for this Olson TE-208 VTVM. It it has a metal case and is nice and big. The button type connectors have been removed. I usually change these to BNCs. I don't think Olson made anything themselves, so this might found under a different brand(s).

thanks - Steve

I think that it should match the RCA VTVM schematic found in their tube manuals (for example, the RC-26) close enough to be useful, it uses the same tubes, and looks a lot like an RCA of the era. Probably the main problem is those grey electrolytic and paper capacitors, I bet if you change all of those and clean the switches it will work just fine.

They all seemed to use the same tube compliment.
The Olson model shown was actually a lot better than some of their earlier VTVM's, that were made by Accurate Instrument, which was some real junk.
My first VTVM was a Knight-Kit with a higher quality meter movement, made by Phaostron. Same tube compliment with a Mullard 12AU7.
I couldn't get excited about the probes that came with it, so I bought an Eico uniprobe.
I still have it, for like 54 years. :thmbsp:

I was thinking this might be a Micronta relative? A predecessor maybe.

Some of the Japanese test equipment was made by Leader, before they made a name for themselves. Decent equipment. :thmbsp:

Yes, it seems to be a very decent meter.
