DFD makes them, but there are a ton on the market. Basically, DMX in and 0 to 10 volts analog output.
Looks like one of the rectifier fuses is missing along with the cap. You can check another channel, but if I remember they take KAA or KAW 30 amp fuses. The breakers provide the 20 amp protection, but the special fuse provides another layer of protection for solid state devices.

I thought the 35's were on the 3.6k dimmers and the 30's were on the 2.4k dimmers? Not sure as it was 30 years ago!Fuses were KAW-A-35.
Original SCR's were wimpy Motorola 35A devices (MCR 3935, I think) with a very low I-Squared-T rating. A short circuit often took out an SCR as well as the fairly expensive fuse. Later units used an International Rectifier SCR with an I-squared-T of about 700 amp-squared seconds. These were bullet-proof and made the fuse redundant.

I believe they used the same SCR on both models, so the 2.4k dimmer had a bit more headroom.
The trickiest part may be if the fuse holder cap is missing. They are hard to find these days, esp the screw on type.
If I wasn't on the other side of the continent, I'd be tempted.I believe we have a dmx-analog converter box that we would sell along with the dimmer packs. Honestly we're just trying to get rid of them so if anyone wants them all we ask is that you pay the cost of shipping.
