Arrgggghhhh! It's become a moot issue for the moment. My Universal 45 color controller quit working (no, it's not the fuse), so I'm out of business until I get it fixed or get a replacement head.
I did get one print before it died, but it only got about 3 seconds exposure! It's quite blue. The yellow channel is what appears to have gone out.
I'll save the solutions I mixed up and hopefully be able to find a Dichro 45s head before they go bad.
