Yes. Originally, I had good output from auxiliary and from the tuner. Now nothing. I ran some voltage tests on the power supply. Looks like I have correct DC voltage just past the rectifiers. None of the outputs show more than 10 or so volts. R05 (fusible resistor is definitely bad. I'm going to rebuild the power supply. I have a list of all capacitors, fused resistors and transistors but am unsure of exact replacements for all transistors. Below is my list or transistors and what I can find for replacements. Does my partial list look correct? And for the two in question, any suggestions?
Thank-you.
Original Replacement
2SD313 AL ……... TIP41C
FS7815M …….. ?
2SB507 …….. ?
2SA992...….... KSA992
2SC1845....…... KSC1845
I agree with Slimecity. Also, Sansui used their own part numbers for a lot of their chips. If you can read a different number directly from the IC or transistor you may be able to search for a cross reference that way. Make sure it is not functioning before replacing it though.
