Re: Resistor exploded in my monitor

:bravo: Thanks, I'm pretty happy with it! The only thing that remains (and this was an issue right after the recap, before the regulator broke down) is that when adjusting the horizontal position, the screen jumps down a few lines when in a specific part of the adjustment range. I also notice a ben...

Re: Resistor exploded in my monitor

I replaced the power regulator with a brand new one (the previous one was salvaged from a broken monitor) and the PSU is perfectly stable again.

Re: Strange part connected to flyback of Atari SC1224

Dielectric = insulation.. That is, it would take for example over 7,500 volts for it to arc though the insulation to whatever its next to ( such as anything metal etc). So you really want that figure as high as possible. I don't know the voltages on those lopt's though, they can be as high as 30,00...

Re: Strange part connected to flyback of Atari SC1224

For now, I'm aiming at replacing the flyback and leaving the tripler in place. Since I'll need to cut the anode cup from the new flyback and connect the new flyback to the tripler, I'm going to have to connect the two HV wires while maintaining proper insulation. I found these instructions today: ht...

Re: Strange part connected to flyback of Atari SC1224

Okay, so the manual actually does mention the tripler as an H.R.T. but no specs are listed.

Re: Strange part connected to flyback of Atari SC1224

Keep the same tripler and replace the flyback if you must ? I'm afraid that the tripler might have worn off, as they tend to. Replacing just the flyback is kind of like going half way. But eventually, if I can't find a suitable tripler replacement, that's just how it's going to have to be. But not ...

Re: Strange part connected to flyback of Atari SC1224

So I think I'm going to have to find a suitable replacement for the tripler. I've seen some of those around, just need to find the specs of the original one but sadly it doesn't have any writings other than OT4 and the service manual doesn't mention it as far as I can tell.

Re: Strange part connected to flyback of Atari SC1224

Okay, thanks guys. I was looking to fix up the monitor with a fresh flyback but now I'll have to find a tripler replacement as well... that is, if I want to give this baby a chance of a long life ahead. Either way, I think it'll be difficult to connect the new flyback to the tripler. The wire that r...
