I use the SW focus motor on all my scopes as well as the tuning of my H alpha etalons eight in total.
While getting things ready this morning, I find not one but two of the handcontrollers wont work!!
Checked and replaced batteries - still not working...
There's not much inside - two push buttons, two resistors, Transistor, Capacitor and variable resistor.
I'm not an electronics type guy......
Has anyone experienced similar failures? If so any ideas of possible cause.
Any assistance gratefully received.
