I'm posting this for reference for anyone in the future.

My Space Invaders Deluxe monitor was a V1001 and picture was nice but it had a slight wave and was stretched. I started with a cap kit from Ian Kellogg. It made the picture better but the main problems were still there. I did a lot of research and read the manual several times.
I came across several threads about a wave in the V1000 series but no one ever really followed up with what fixed it.

When I read the manual, it said b+ should have around 75vdc. To test this, put an alligator clip onto Pin 2 along the outside. Red to the other end of the alligator and black to ground. It is adjustable at R212 on the board. Mine was pushing around 91vdc.

Next step for me was to replace the voltage regulator. The manual calls for
2N5632, but I found that is obsolete, so its equivalent is NTE284. It is a bottle cap style at Q101. I replaced that easily, no solder is needed and the monitor is now perfect.

I have attached a before and after and a photo of the chassis map.
