dibateg Posted October 12, 2023 Share Posted October 12, 2023 Has anyone ever had one of these apart to repair? It looks like the output transistors have blown, but there are no identifying numbers on them. I've not been able to find a circuit diagram or anty tech details online either.... At least if I knew the transistor types, I could replace them. Tony Link to post Share on other sites More sharing options...

I have 2 OnTrack single units and planned to change all my controllers to OnTrack but couldn't find another when I wanted one so had to use a Morley double unit when I would have preferred another single (The OnTrack and Morley Hand helds interchange if you swap the connectors) Link to post Share on other sites More sharing options...

dibateg Posted October 16, 2023 Author Share Posted October 16, 2023 As I understand it, they are discontinued ( although I didn't ask ), I know some guys have been trying to get second hand ones when they can find them. Regards Tony Link to post Share on other sites More sharing options...
