RE: 19V2000 blowing F101 and F102

Nevermind. I cleaned the HV diode connections and put a little pigtail in each end of the diode so it would make better connection. Now it’s a rock steady 14kV. John Robertson tried to help me with this monitor ten years ago and I never got back to him. Although I suspect you don’t remember and I hope you’re not mad John but, I had to drop it due to RL intervention. However, I used the B&W Vector Monitor FAQ guide to help me so, in a way, you were still helping me since you contributed to the FAQ.

A very belated thanks.

Robert

Okay, so I did a HV cap kit; replaced the HV rectifier with an VARO 1812 diode and replaced the bridge rectifier. It no longer blows a fuse but, it is blooming like a pulsating heart and I only read about 7KV of high voltage. I cannot adjust it any higher. Can someone suggest something else?

Thanks.

I have a 19V2000 in an Asteroids Deluxe and, after about ten minutes, it blows F101 and F102. Looking at the prints, it seems that it feeds the 38V to the high voltage board. The surprising thing is that it blows both a 5 amp and the 1 amp fuse with only a diode separating them. Since this is heat related, I'm looking for suggestions as to what's likely to need replacement based on the experience of the community around here. I haven't put a cap kit on it yet but, what else should I look for?

Does the bridge rectifier (DB100) fail often? How about C900? Does that ever fail shorted?

Many thanks.
