I lost the scale illumination in my 465 I checked Q1570 which is replaceable with an MPSU45 NPN darlington according to the manual. It shows shorted from collector to emitter. Am I on the wrong track possibly? If not does anyone have an idea for a replacement? I checked alltransistor and it says there is about 1 replacement and its a MPSU45 so that didn't help much.
Thanks guys
