Dumble ODS 50 watts schematic?

[jay18]

Hi,

First of al I have to say this is a great discussion board. Learned a lot here!

I'm searching for correct schematics of a Dumble Overdrive Special 50 watts (did they exist, or were to just switchable from 100 to 50 watts?).
I would also like to know what the term "HRM" means, which I read often here.
Hope you can help me.

Thanks!

If you search on posts by ayan and Glaswerk, you should find some good information about the differences between 50 & 100W ODSs. Some are in the form of recommendations [ps filter caps] and others observations [NFB values] of original 50Ws.
