I recently purchased a space invaders deluxe but when I power it ok there is only a scrambled line on the screen and the game didn't playing blind. I measured the +5, -5, and the +12 and they all seemed within acceptable range. The reset circuit was at .023v which I believe is ok. On the board however the +5 was low at about 4.6 and the -5 was high at about 5.4. The audio was also very low at about 4.6 when its supposed to be near 18. I'm not sure if its a board or power problem but if anyone has any advice I would appriciate it. Thanks.

I also took a photo of a resistor that I noticed looked rusty, I thought that it might be one problem area.

I would buy one of the power supply rebuild kits from Bob Roberts.

in fact, I need to do that myself, even though my SID runs fine. 30+ year old electronics kind of frighten me.
