I used the search asking "Yamaha G100" and this came up on top:

Is that useful?

Unfortunately all your links are not helpful.
http://www.ampix.org/albums/userpics...0_series_I.pdf lacks pre-amp and tremolo circuitry

https://www.owner-manuals.com/-manua...a_filter_id=71 doesn't contain schematic for G100-212 I

etc

There it is https://www.analogalley.com/osccart/...22478e156003f4
But costs 14 bucks

Yamaha had more G100 models than Campbell's has soup.

Here are all of the G100 versions that I have: G100.zip

If you do not have a problem, please upload photo chassis inside (layout with PCB) and the front and back panels of your amp to get an idea of what exactly model is your Yamaha G100-212.

Personally, I think 14$ is not an unreachable price if you really need the technical documentation.
If you take Yamaha G100-212 technical documentation be kind and share (upload) with us (music-electronics-forum)

G100 Schematic

This one? The 2-12" model should have the same circuit.

Hi there!

I'm looking for the schematic for the Yamaha "Hundred B212" (this is what it says on the front). The backplate says "Model G100B-212"

What is the correct schematic for this model?

[JAelec]

Oh I think I found it in Jazz P Bass's zip archive above...
