Hello, I have a 1986 F250 6.9l with every dash light out. I have stripped the dash down and determined it wasn't simply burnt out lamps.

I just bought the truck, it has an aftermarket stereo. The rest of the electricals work properly.

I am thinking it is a bad dimmer or the stereo causing this?

Thanks for your help.

Have you checked the fuse?

Yup, every fuse in it is new.

It Could be the dimmer.

Are you talking about just the illumination lamps, or even the warning & indicator lamps, too? The illumination circuit is LB/R & comes from the headlamp switch's potentiometer. The terminals on the headlight switch & its connector are known to burn, so inspect them carefully.
