CRT discharge tools are not in high demand, so it isn't easy to find one that's designed for it. While this is very much the case, you can use a flathead screwdriver and a heavy gauge wire with alligator clips on both ends. As long as it can handle 15-25,000 volts, it’ll work. If you have them, use car jumper cables; that will take it without a problem. It’s usually 15,000 volts for small CRT’s and 25,000 volts for the larger sets. This CAN KILL you.

If you have them, use car jumper cables; that will take it without a problem. It’s usually 15,000 volts for small CRT’s and 25,000 volts for the larger sets. This CAN KILL you.
 
The most critical advice I can give you is to use an electricians screwdriver as a safety net. Yes, these are expensive but it’s better then dying because you used a cheap screwdriver with little to no rubber on the handle. This is the one thing I’m not going to budge on. I’d also recommend electrician gloves as another safety net that can save your life in the worst case scenario.
 
The big thing is to find the service manual to figure out what each adjustment does, as the points are unlabeled. Get it wrong and it’ll NEVER be right again without hours of tinkering. The main reason to do this is to adjust the system to compensate for the wear of the CRT as it ages. If you keep having to do it, the actual CRT is in need of replacement and is worn out.
 
If you have to replace it, do not settle; find a good one with few hours and no burn-in. Used ones with heavy use and burn-in should be considered scrap as these typically do not last very long.

This tool isn't exactlyCRT discharge tools are not in demand. Quite frankly,high demand, so it isn't easy to find one that's designed for it. While this is very much the case, you can use a insulated flathead will doscrewdriver and a wire that has alligator clips on both ends that also uses a heavy wire gauge. The big requirement is it has to be able to handle ~15,000 volts or more, which means the same thing aswire gauge needs to be on the Apple tool did. Thesethick side. Yes, that number is not a lie. The average desktop CRT can hold up to 15,000~15,000 volts foror more in some cases. Larger CRT's can hold ~25,000 volts in some cases. This is enough to severly injure you, or potentially even KILL you.
I don't exactly think you should use
a desktop CRT so when I say insulated, I'm serious. Also, thick rubberscrewdriver and alligator clip test lead in place of a discharge tool, but it does work in lieu of the actual tool.
