FYI my browser (Firefox) warned me that link was 'untrusted'.  Simply by removing the 's' in https, fixed that issue.

I'm expecting an AG-25 tomorrow, so if anyone has a need, I'll open it up and take some hi-resolution pictures of it.

I'm still also looking for similar information for a Mirage KP-2 440 preamp.
