The simple electronics on my old ProForm Air Stepper has failed. The electronics control a very small motor/drive gear which simply tightens a belt on a flywheel. Low power stuff.
There are 2 modes: programmed and manual. Programmed, which takes the user through 10 or so adjustable sliders failed a year ago. Manual, which is a single adjustable slider, failed last week.
Board says "FOX BIKE" but no id numbers. No bad solder joints that I can detect.
I see that there are 2 identical circuits composed of [my guess] a transistor and an SCR [both TO-92 cases] which power the drive motor. I surmise that one was for the programmed mode, the other for manual.
I'd like to replace these components but am stumped.
The final drive device is labled "A934 RH" [Or could be 4934 RH], the other device is labled "C 2060 RG."
Mouser cataloge and the internet failed to help me.
Can anyone tell me what these devices are and/or substuitutes?
Thank you.
