Here is a picture of the internal of my Vanguard. As you can see the ugly power switching supply is gone and replaced by original equipment donated by Etiènne. Thanks, mate.
The only thing missing is the metal plate behind the game board, but I can live with that.
And here a few pictures from the frontside. I love the effect of the monitor bezel, it gives a lot of extra atmosphere when you are playing a game.
As so often, the photo doesn´t do justice to the game picture. In reality it is very crisp, colourfull and the screeen has no burn in.
After the fix of the main game board by Robin last weekend, I still had an issue with the speach synthesizer board. Yesterday I noticed that it was not working good, there was a lot of sound distortion. But Robin showed me that a simple cleaning job of the eprom pins could solve a lot. So I cleaned the eproms on the synthesizer board and yes ...... speach is now working 100%
Last small things to do is adding a coin door lock, getting some new light bulbs in the coin door (is there a Dutch retail shop where you can get 6.3V bulbs with bajonet fitting?) and cleaning the CPO according Robin´s magical treatment. (Flatten it with a hair dryer and get rid of cigarette burns through sanding and polishing).
I still have one question though, both Robin´s Vanguard and my Vanguard have a lot of static noise when showing the attract screen. But when you start a game, this static noise disappears almost completely after a few seconds. Until ´game over´ that is. Why is that and what can we do to get rid of the static noise?
