Spectra RF Bd repair HRN6003D
Posted: Fri Nov 09, 2007 5:47 pm
I have several Spectra 450 & 800 RF boards HRN6003 or HRN6010 with a chip resistor R633 82K that has been hot. Some burned the board and the trace. This seems to be a common problem. I really don't see anything on the schematic that would cause this type of current. Perhapes it is a trace onthe multilayer shorted. Any thoughts on repair.
