Yamaha PG1 preamp

[g1]

Anyone have a schem for the Yamaha PG1 preamp? I have the G100III which is close but there are some differences.

The support site doesn't have schematics. It has a description, and a couple basic service bulletins.

What problem are you having?

Cool.

Thanks vintagekiki !

Enzo, problems with channel switching, parametric, and power supply. Have only verified supply fault so far but thought I'd check for proper schem anyway.

I don't know if this file is working, but...

You have to be authorized service or dealer to access that. Thanks anyway.

It won't open, adobe reader says the file is damaged. Can you save as html, then zip and post?

[Enzo]

You are right, I cannot open the file I saved. I have so far been unsuccessful downloading and saving the file in any format, let alone zipping and sending back out.
