Re: G05-805 -vs- 15V200

I had a blooming problem on my Asteroids' 19V2000 (which was originally in a Battlezone judging from the burn-in). I'm not sure how different the 15" version is, but FWIW my experience was...

My diode (D903) was an H1809. I found it for sale at arcadechips.com. The old one had goop all over it; some of it was likely a high voltage grease (silicone?) but some of it seemed more like melted plastic/rubber. I had a hell of a time getting it out of the rubber boots on the ends. Eventually the heat-gun trick I read about (perhaps in the vectorlist archive) worked great. After I got it out, I discovered that one of the metal caps & springs was only hanging onto the wire by a thread. I had to make a spring out of a pen spring an re-solder everything back to some freshly stripped wire. After that, re-assembling with the new diode was very straightforward. I used a light coat of dielectric (for spark plugs) on the ends of the diode. Not sure if that's the "right" thing to do or not. I think it's just there to prevent corrosion. It fixed the blooming problem, BTW.

Oh, and it may be a good idea to discharge the tube before messing with it (I'm sure you already know that, though).

I also replaced the caps while I had it apart (Bob Roberts' kit). But I didn't really notice a difference between before and after. The other problems I had with it were (1) the obligatory bad header joints and (2) a dirty pot causing intermittent jumpyness and occational collapse on the X-axis.

Regards,
Darren
