Runway lighting controller on the fritz

The Fly-By-Night switch that permits radio control of our runway lights has gone on the fritz. Unfortunately, it’s an older unit, a BB-7, built by Subil Enterprises, which is now out of business. The new company has no association with the original.

Does anyone have a schematic or other manual for this system that they will loan us? Does anyone have any experience with this system and can help us get back into operation?
