We have this old dimmer/control pack from the late 80s / early 90s, and we were wondering if anyone had any idea on what they could be, and if there's anything left that could still potentially control it. If anyone has any ideas as to what they could be or any links that may be hard to find please let us know!! :D

Looks to be some sort of cobbled TTI dimming rack. Your best bet is to give Literol a call http://www.litetrol.com/ and explain what you have. They are pretty good at figuring out the older systems.
 
TTI was a brand of dimmers. These are probably from the seventies or eighties. They run on analog control. I didn't work with TTI much, so I don't know the analog control voltage. Obviously, you are missing one dimmer card and don't know the status of the others.
More information here.

Steve Short at Litetrol would be my go to source for info.

There are DMX to analog converters. You can also find analog consoles on ebay like this one. I don't know if it will work with TTI dimmers.

Because of the state of disrepair, I would recommend getting it checked out by someone that is familiar with this equipment. Check for local theatrical lighting rental shops in your area.
Take care,

This looks like a custom TTI dimming system using a later model card dimmer, plus 3 relay units for the flourescents ?! Maybe. The blue is TTI color, but I've never seen that dimmer. The standard TTI system was a blue box with 6 dimmers. These use an analog control signal, 0-10 vdc. The male connectors are the standard Cinch Jones 6 circuit control connectors. These look like the end at the dimmer rack for cables run from a booth maybe ?.

TTI was in Connecticut, has long been out of business. Agree with others that Steve Short at Litetrol is a good company to do any repairs, if needed, though if you are in Texas, it'll be expensive. Is there a local lighting rental shop thats been in business 30-40 years ?? Maybe LightParts in Austin, TX.

The three "relay units" (well, the two where the labeling is visible in the picture) are labeled "control" and would seem to each control the six dimmers to their left. The fluorescent light control, if that's what FLUOR refers to, would appear to be elsewhere. (It's noteworthy that the "FLUOR" connector is a female while the three for the dimmers are males, hinting that it might be an output of some sort from the dimmer box rather than an input?)

The control modules have a switch to select between 10, 5 (I think), and off. I'd guess that's to choose the control voltage.
 
I concur that it is definitely TTI (Theatre Techniques Inc) pack with eighteen single 2400 watt dimmer modules. Each set of six controlled by a control card. Very probably 0-10vdc control voltage which are on the Cinch-Jones 10-pin plugs. Pins 1 thru 6 are positive for dimmers 1-6 with pin 8 being negative common. Any 0-10 analog console with do the job or DMX to 1-10vdc converters are available on eBay or in PC board form from Northlight DMX. Actually a not-so-common TTI product I think.
 
They are TTI RP dimmers. I believe I still have parts. I have tons of cinch jones connectors in new stock i would love to loose. It looks like you have 6 dimmers per phase, but missing 1 dimmer card ( i might have). Dead caps are its big failure.

The blue controller is either 0-10 or 0-12v. same with the dimmers; they could be trimmed to either. I will say the controller has nice wire-wound pots in it. I know of at least one music venue still running lights on one.
