Re: Avometer HRM-rotary selector switches
Dave,
The characteristics of general purpose germanium diodes are very similar to these Westinghouse copper oxide rectifiers. You should find OA85s or OA91s will give accurate results.
If you would like a copy of the Westinghouse data booklet on instrument rectifiers, please send me a private message and I will put a scan of the booklet in a Dropbox for you.
