Hello to the group I obtained 2 of these units at the last MIT flea. Both not working correctly. Virtually no documentation on the internet. I recall that 2 years ago someone else asked EGG info also and no real responses. That said I can tell you a few things. There is a diagram on the unit that shows the 16 connections. Its accurate. +24 requires up to 1.5A cold and drops to 300-400 ma hot +5 for the synthesizer draws a constant 300 ma It seems you can start the RB up without the +5 RB and synthesizer are quite separate.
The EGGs seem to have a fair amount of reserve RB gas in the lamp. The two units I have have high lamp voltages even though they were mid 1990s. Both units were bad. The problem is the 470 uf @25 V 15 volt bypass caps and a regulator cap 270 uf @16V. It literally fell apart when I was removing it. One of the 470 UFcaps read 1UF esr 2.6 ohms Replaced with high temp 50 V equivalents and both units startup and automatically lock in about 5 minutes. Changing these caps also put the units back into specification for stability. So there you have it the total EG&G cookbook of RBs. Good luck and they do seem to be a fine unit. Regards Paul.
