[TenTec] Omni D quits after 60-90 minutes

[Stuart Rohre]

Tom,
Your further info prompts me to suggest putting De-oxit on all switching 
contacts of rotary switches and exercising each switch a bit, to spread 
the contact cleaner/ lubricant.

You should also inspect each contact for burned or pitted spots while 
you have the high intensity light and magnifier at hand.

Of course an unsoldered or poor solder joint on any switch lug could 
produce such symptoms as well.

Good Luck,
Stuart Rohre
