Great Aristocrat schematics - a power supply schematic with NO parts values.

I need the value for R7 on top of the power supply board. It burned up REEEAL good.

Another resistor, marked 22 with a K below it reads 2 Ohms with my meter. It is part of the base bias on a transistor for the 12VDC supply.
I can't believe this resistor is 2 Ohms and not 22K but even after removing the corresponding transistor the resistor still reads 2 Ohms.

Marked schematics, parts values, any help would be appreciated.

I'm not near the machine right now but it is the slot with the linear power supply (that slides out for service) in the upper left side of the top shelf.

Also what is the key switch mounted on the outside left edge of the belly glass used for?

The outside (right side of machine) key switch has been pulled back inside the machine for some reason, on both machines we are working on.

what is (was) this key switch used for?

I'll get back top you on the madel number when i get back to the shop but hopefully you can answer the above questions in the meantime?

Greetings,
The key on the left turns on the lights by the meters to the right of the power supply.  The key on the right resets the machine after a jackpot or large cash out.
Assuming we have similar machines...
R-7 and R-4 are labeled "xw2  R22  K"
R-3 is labeled "xw2  270R  K"
Hope this helps.  The folks here coached me through the resurrection of my Aristocrat.  You have to fix the power supply to find out what else needs to be fixed.
Best of Luck,
   Keith

It's raining Aristocrats! We got another one into the shop with a power supply problem and this one had a blown transistor on the power supply so I was able to remove a good resistor and read it. It measured .22 Ohms. Got them on order and hope to get them in soon.

BTW Jameco Electronics had those small TO-92 transistors on the power supply, plus the TIP42.

Thanks for the info on the switches!

Keith, congrats on getting your Aristocrat working! (I think I sold you a parts machine a year or 2 ago when I gave up trying to fix mine)
