Thanks for the tip.? On one, the 10ohm (yep, 10) is cooked, so I need to
get another one.? Looks like 1/2W, but anyone know for sure?? The
schematic just notes the resistance and identifier.? It could be 1W...
The other 1 I have on the bench looks to have a good resistor, but I
will check the VR next.

Shouldn't be too difficult to troubleshoot;
have you got the manual?
Start by checking the 24V > 12V regulator...
Second that! I've had to
replace more than one regulator on 848s; also
the 100 ohm resistor (R1) and electrolytic capacitor(C6) on the input
side of the regulator.
