UPDATE!!! Long overdue. Some very exciting things are happening. I've complete the XY deflection, High voltage section and crt driver for a plug and play kit that will work for most 5"-9" crt's and ordered the parts for a small run. James Sweet has also finished his vector daughter board. A board that plugs onto a cheap Altera Cyclone FPGA board and so far lets you run Asteroids and Asteroids Deluxe for true hardware goodness. I've added a couple pictures of the prototype deflection and James FPGA board running on a vectrex crt. The screenshot is terrible, but trust me it looks amazing in person.

New tiny deflection pcb's arrived and assembled. These run off from + - 12v and are good for 5-9" crt's. They also can replace the deflection in a vectrex and enable the vectrex to run arcade games with a great picture.

LONG OVER DUE UPDATE - Completed a 5" crt XY monitor with a smaller deflection design and stand alone high voltage pcb.

I ordered most of the parts to begin work on the CRT neck board. I also have a updated High Voltage circuit. I want to get the High Voltage PCB s designed and produced soon along with CRT neck PCB s.

Schematic of high voltage. I did not build the shut down circuit that is in the slotted box and added it just for reference in the schematic. I may add it at a later date, but as drawn it probably will not function right so leave it off if your going to build a prototype. If anyone has a place to host files and stuff for this project let me know and I will email all the files for you to host. Thanks

I have built a prototype HV power supply and now have a fully functioning XY monitor. The only thing I am using that is not built from scratch is the neck pcb from a TV. Here it is! Asteroids on my 9" color xy test monitor. The China power supply only outputs 98V max, it would have been better to have around 125V for b+, but for a test monitor it works fine. If anyone builds this be warned you are dealing with high voltages that can be lethal. I am not a high voltage design expert, if you see a way to improve this please test it ouT and let me know. I will post the schematics shortly.
I also have 2 new complete assembled tested working deflections pcb's for sale if anyone is interested. I have left mine running for days and days they are bulletproof. Heatsink is not included.

Okay I have settled on a elegant and cheap solution to making the High Voltage.
If you want to follow a long you will need to buy one each of these items.
2SD2599 or equivalent Hot transistor. Most of the newer hot transistors will work. (I used one out of a 13" TV)
One of these SMPS.
This flyback is the one I settled on because it is cheap and available.
555 timer, A few fast switching diodes (UF4007), 2n2222, some resistors, capacitors and misc. Most stuff any good parts bin will have.
Some of you might ask why did you not use a WG6100 or Amplifone flyback. The answer is simply because it was cheaper to use the above components. The WG and Amplifone flybacks are $40 or so each (I even asked about price breaks). All the parts to build the version I made should be less than that to build with all new parts. I was thinking about designing a pcb with a SMPS for B+ when I found that the Chinese already built one for less than $10.
Stay tuned for lots of updates and in the mean time collect up some parts.

I have been collecting components up for the next section of the project the high voltage section. I am still undecided on whether to use a repro wells wg6100 flyback or adapt a common TV flyback. Any thoughts on this would be appreciated.
I also purchased a Vectrex to experiment with. These are a neat vintage vector based games system if you didn't already know.

Now I need to get my Space duel PCB working so I can run a color XY game.
Notice I used a 13" pirates of the caribbean themed TV from a thrift store :) .
Asteroids with RED Gun
Asteroids with Green Gun
and finally with blue Gun
