Bryson,
Thanks for the link to the datasheet. It's not linked on OpAmp's main page, so I didn't know it was there.
Personally, I think it's a shame to part out unusual old consoles, but hey--it's your choice. Here's a schematic for the 12-channel version of that console:

How about trying to sell it intact before resigning to part it out?
PRR,
I only have seven of the 325L, so I'm reluctant to sacrifice one to science. I'm pretty sure OpAmp modules--at least the small signal models--are potted. But perhaps Bel from OpAmp would be willing to divulge some info about what's inside, since it appears to be a discontinued product.
