Astro Blaster Z-80 Arcade Machine Help

bluemanop:
I have gone through most of the resistors on the power supply board. It seems that there are some discrepancies in some of the resistors. I.E. 4.7k resistor is metering out at 2k or 1k.

I am currently looking around for cheap prices on the net like Jameco.com but I plan on checking out a couple local electronics places as well.

Just in case anyone that doesn't have an astro blaster machine out there but is following this thread for general repair information. Here is a good link for reading color bands on resistors if you don't have a parts list and/or schematic and want to meter some resistors.
