Not sure what pins you want me to check based on the schematic of the power supply. I brought it up and cut the schematic in half, looking at this view I can see the pins you are referring to on the right hand side. I'm just wonder where I can find that on the power supply board.
I will try to go by my friends house and take a good look at the power supply board and I think I might be able to take the power supply with me to test it from home as well. Even better I will take a really sharp picture of it and post what I see. In the mean time I included what I am looking at in this post, just to make sure we are on the same page.

The pin numbers I referenced would be for the connector to the main game board. I'm not sure how the board is connected, so I can't be any more specific. Those pin numbers came right out of the schematic. Looking at the schem and the supply, you should be able to correlate those terminal numbers.
While testing the supply on a bench at home would be easier, it would be best to test it connected to the game so that the supply is under a load and your measurements are accurate for actual conditions.

I believe I can borrow the spare cage assembly and the power supply. I will let post some pictures as soon as I get over there this week.

Well I got over to my friends house and pulled the power supply and took the cage with all the boards in it. I will get to testing the voltages from the pin outs this week.
Here is a good question, if the old monitor in the astro blaster is a typical RGB monitor found in arcade machines. Could an equally old Amiga or Mac RGB monitor be a good sub if I were to find the pin out configurations of the monitor? Basically what I am trying to do is make a good test rig from my house that would give me a video screen at least.
I'm going to go research this on the net for a bit. Anyone got any ideas for this or has utilized an old RGB monitor for this purpose?

Ok, I'm back. Work hasn't completely taken over my life.
Here are my results:
