What I am trying to determine is why the AM-10 part in the CA-227 is slightly modified?
Jim
We're probably looking at the same AM10 schemo, then.  No help from me, sorry, hope you get some pics.
But hey, if D Jensen had something to do with this, then maybe John Hardy or Steve Hogan could shed some light?
 
As an aside... an AM10 may be useful as a 2520 footprint DOA...

Something like this?

I just went to your site and saw that it's been there for years  ::)

Did you use this in a mic pre? What kind of trafos did you use?
 
Mitsos

I actually built it & tested it for a couple of hours on the bench, but since then have not used it much. I use it whenever I am short of a DOA & just stick it into the prototype I am building for testing purposes....
