You really don't want to use those things. You will do so much better
using an outboard preamp, it's not funny.

I have schematics for the things if you want to build your own. It is
basically two transistors, a coupling cap, and a handful of ressistors
with the worst godawful transformer Beyer ever made, and an octal plug.

As I recall, you can't use the preamp modules from the PR-10 because
the power supply voltages aren't high enough.

But really, don't use the plug-in preamps. Your ears will thank you.

Well this is not for me actually... I got the AG-500 unit from an old radio
station and never had any intention of using it so I sold it on ebay to a
guy but it only had one preamp... he wants another one... Any leads on
another preamp would be appreciated

Ask on the Ampex mailing list. I would suspect that most of the ones
out there hit the trashcans years ago, but if there are any left, the
Ampex mailing list guys will know who has one in a junk drawer somewhere.

You really should warn the guy who buys the machine against using the
horrid things, though.
