OA-2212 Schematics

[peterbsmith]

Hi Sonab community!

I'm in California trying to restore a pair of OA-2212s, and I am hoping to find some schematics. Are there any to be dug up? I understand there are also a set of filter replacement instructions that are relevant. I would be much obliged. . .Thank you, Pete

Hi Pete

In order to give a good answer i must understand what you are interested in.

- There is a modification available for use with new drivers developed for Sonab speakers.
- There is a modification developed by Stig Carlsson to improve the 2212 with original drivers
- There is also the original schematic.

What are you planning to do?

Best regards

Martin

Hi Martin!

Thank you as always for your reply. I am looking for ANY information that will help me learn more. I have already refoamed the original drivers, and I want to keep them if possible, so I would be looking for the upgrade list for these. I also could really use the original schematics, so that I know what I am starting with. These MUST be brought back from Sonab purgatory!

Thanks again, Martin,
Pete
