Argh! I have two of these boards from Asteroids Deluxe machines that have had a burnout on the Y deflection side. I have rebuilt both of them with the exception of VDR 600. Does anyone know what the specs need to be, or otherwise what a suitable replacement would work for this particular varistor? The manual shows both VDR600 and VDR700 being the same, but there are no identifying stamps on the components.
 
Thanks a lot! :D Just out of curiosity, have you used them before in your repairs? Looks like a cool little product.
 
What lilypad said. You should not need to replace that. Even if it has soot on it from other nearby failures, it's going to be fine. Clean the soot and char off with Goof Off and Qtips.

They don't go bad. Keep the original and test the board with it, after you fix everything else. (And be aware that you have to find and replace EVERY bad transistor, resistor, and diode, otherwise it'll likely fry again when you power it up.)

If you can't figure it out yourself, I repair these.

that V2000 I've messaged you about 800 times, the VDR600 was collateral damage from exploded resistors a few times and it still works. LOL

just FYI I think C603 being domed and testing very bad was the cause of that happening repeatedly. it was difficult to see but I just happened to catch it out of the corner of my eye like "whoa wtf". I'm uncertain how it would work like that between 2 weeks/2-5 months.

that being said, what andrewb is saying, you have to extensively test every part in the bad section. and if you skip a step somewhere, you'll lose all your progress. that V2000 was highly educational for me and vector monitors. the only element I don't really do is the HV cage unless it's getting solder fixed or caps replaced.
