No displays are working but I'm pretty sure I'm in the right spot.

The high voltage section of the driver/solinoid board has some blown parts.

The online schematic is not showing what R74 is.
And I don't know what the other blown part is to the left of the right capacitor.
I pretty much need a shopping list of about 5 parts in this picture if anybody can help.

I know big daddy just upped their minimum order amount. But you can take that list Wariodolby posted and check out Electronic surplus for a lot of the parts. Just type in the part number.


And check this out. Has most all info you may need.

Any time you find burnt resistors in the high voltage section, that generally means one or more (usually all three) transistors in that section are SHORTED.
