WTB: atari star wars deflection board

good question. a previous repair guy removed it and never came back. the HV board was replaced with a raster board and dummy yoke, see pic. i dont know if the crt was replaced or not . do you need to know that? the owner said it worked for a month then stopped. he doesnt remember, but im guessing he called the guy back and they guy removed the board, otherwise it never would have worked. maybe it better to replace the HV board too? with the defection board missing, the yoke wire is dangling, as well as the larger plug you see me holding in the pics. i repair pinball games, and he asked me to repair the atari. i know a bit about raster monitors, not a lot about vectors. let me know.

thanks mike

That is an Amplifone setup, which is the better and more sought after of the two vector monitors used in Star Wars (the other being the WG6100, which was used in most of the other Atari color vector games).

I have deflection boards available, like the one below. That particular one sold, but I have another like it. Same price, terms, and warranty.

You might be able to get it working with that raster chassis that was used in place of the Amplifone HV board (which were prone to issues, due to the original flybacks failing). I posted a link to the Amplifone FAQ in your other thread, which explains how other chassis were used in place of the Amp HV board.

I may have a rebuilt original Amp HV board available (with new modern repro flyback that won't fail), but it isn't going to be cheap, and will be more than the deflection board. I haven't rebuilt it yet, but I was planning to soon.
 
Ha, there's a hack I have not seen in quite a few years...
using the HV setup from a well gardner 4600 to drive a Amplifone.
to put that back to original you will need a Ampllfone deflection board
and a High Voltage board.

Wow...I had never heard of this or that this was even possible...as it appeared to have at least worked for a while, would one expect that to last in general?

Obviously you'd probably want to restore this to the normal, correct type of setup (Amplifone HV and deflection boards), but I'm still curious...

It's really not that bad of a hack, as 19.5kV is 19.5kV, and a tube is a tube, pretty much. It looks ugly, but given the cost and rarity of Amp HV boards (compared to 4600 chassis), if you just want the game to work, it's a practical means to an end. I got a kick out of it when I read the FAQ and saw it. There's a lot of interesting stuff in these docs that were written way back.

The 4600 chassis doesn't really know it isn't driving a raster tube, so it shouldn't know the difference. You're maybe drawing more power than what just the Amp HV would draw, but who really cares, as long as it's wired safely.

John from Flippers in the far northwest did this years ago and documented it back in the RGVAC days. I don't know if he was the first or not, but I recall him posting it with pictures of it working.
 
that was one of the only options before the wintrons were released...
and they were quite pricey also. I have only seen one ever, but it
worked well.

dezbaz on the forums here created reproduction and universal HV replacement boards. Not sure if they are available, but that is another (cleaner) option than using the raster chassis and yoke to produce the HV for the amplifone.

He also produced Amplifone deflection boards too.
