Regarding the OP, I just pulled one out of service. The station donated it to the local historical society (sounds weird to put a console that new into a museum...). It was heavily modified and in need of recapping. I recapped a few input modules, and found the foil wasn't very rugged, so be easy when you do it. I also learned early on (back in college) that the speaker amp in those boards can oscillate and run away if you use 8451 as speaker wire.
