I've got a San Fransisco Rush with a chassis that is either NT-27E or 2701.. I am not 100% sure.. but it had originally blown the hot.. I then swapped in a new flyback (MRCFT-249) and d1879 HOT.. It worked for about 30 minutes before blowing the hot again...
I isolated and checked out the power supply voltages.. they all check out good.. is it possible my replacement flyback is bad? Or my yoke has burned up?
I checked the horizontal inductance of my yoke and it reads pretty low... about 0.265mH
My board doesn't exactly match up perfectly with the normal schematics available on arcade archive.. namely R424 (820ohm 5W) which is a 3.3Kohm 5W in the schematic..
