| Will this work (CRT Discharge cable for Plus)? |
Posted by: 68kPlus on 2022-09-01 02:11:46
This is my new CRT discharger.
It has a 5A cable connected to a rubber-insulated screwdriver.
Will it work connected the way it is? I can't connect it normally because the cable slips off.
Thanks! |

If there's good contact between that clip and the screwdriver and the clip won't fall off, yes that's fine.
P.S. Is it OK if you use descriptive thread titles in future? Thanks |

I think the contact is okay. I am worried about the screw on the Plus though, as it is rather large and this clip is rather small.
I guess time will tell!
Sorry about the lacking title, next time I will make them more descriptive!
Thanks |

To be honest, i had never used a CRT discharger (only the very first one i was extremely cautious, probably too much) never had any issue.
Probably not a safe advise, but never seen any issue so far.
Just use a good screwdriver with a rubber handle, use a cable to ground to play it safer. |

All the people that didn't survive working on charged CRTs aren't here to tell us about it.

You are probably right, but i lost count of how many Compact Macs (probably several hundred) i have been messing around, hardly seen a spark once or twice.
On the safe side, i remove the mains cable and toggle the switch a couple of times.
Most have bleeder resistors, so the CRT self discharges in a couple of seconds.
Again, the first one i was extremely cautious, doing it by the book, but after a while.... |

OK, so I am what I would consider careless and tend to work on "steer clear of the angry bit" and haven't ever needed to remove a neckboard, but toggling the powerswitch and gambling that the bleed resistor is in good condition isn't great. At least leave it for a few hours, there is no need to rush on a 30+ year old machine.
Look after yourself, you can always replace a compact mac, but you've only got one heart. |

Most have bleeder resistors, so the CRT self discharges in a couple of seconds. But, there is every chance that resistor doesn't work anymore, and you won't know until its too late... this is why we must dischage even if the risk is low or we think its unlikely to get a shock.
The worst I've done is power up a Classic with the anode cap not attached... spicy noises and I think I was lucky nothing more than that happened. |

I got a Dell UltraScan 15 from 1993 and I'm not sure if it has a bleeder or not. Should have already made a discharge tool ages ago, honestly...
The issue with this one is that the light kinda bleeds a bit off of GUI elements. |

Bleeder resistors and the like are a supplement to safe working practices and not a replacement for them.
I cannot boldface that enough.
Do not assume they will work, do not assume their presence. Just be grateful if they save you. |

Do SEs have bleeders? Yes, but the question/answer is irrelevant for the sake of safety - you must discharge if you plan on touching the CRT/AB anyway. |
Posted by: 68kPlus on 2022-09-02 20:40:33
