Train America Studios UCUB Question

You could email Mike Reagan, who owned TAS, and perhaps he will contact his friend and colleague,  Bob Krivacic who designed the UCUB, I believe.  They are the experts.

Bob posts here, and is the real expert on the TAS hardware.

Any idea how do I get a hold of Bob?
Thanks,

I'm loathe to give out Bob's email, but Mike Reagan's email is readily available through this website.  Start with Mike would be my suggestion.  He may have the answer and if he doesn't, he can pass along your inquiry to Bob.

Bob Krivacic is on the OGR Forum.  You could search for his account.  Landsteiner's suggestion is the best for a quick contact, though...contact Bob through Mike R. if you can't locate Bob on the Forum.

I've known Bob for nearly 25 years and he's almost always willing to help.

You should really have an email in your profile so people can contact you.

GRJ,

Yup. I only had my email filled in for admin access. I updated my email in my profile so it should be visible now 🤫

I was able to get in touch with Bob and he provided the answers I was looking for. In case anyone is interested, here are the steps to convert an AC UCUB board to DC:
•swap out the two jumpers from the underside of the board with a bridge rectifier (orientation is silkscreened on the board)
•remove the green motor field wire from “D” and jump the black wire from “C” to “D” (yellow & blue motor brush wires are soldered to “A” & “B”)

And that’s it.

Thanks again for your help!
