Bleeder resistors / CRTs

[smrieck511]

First, I want say that everyone should discharge CRTs any time you're getting into the analog board and CRT areas. It's simple and makes no sense not to.

But I noticed something curious working on 3 SE's for the last 6 months or so.
I've never gotten even a tiny spark at all even when discharging the CRT a second after switching it off and pulling out the power cord.
My CRT discharge tool has continuity so I know I'm doing it correctly.

It seems that the bleeder resistor drains all or most of the voltage instantly at least on the SE analog board? Anybody encountered a faulty bleeder resistor that didn't do this?

Just wondering...

What I've always heard is that all the Macs with in-built CRTs have bleeder resistors except for the early Mac Plus systems and prior. Feel free to correct me if I'm wrong.

Of course the advice I've always heard (which makes sense) is that you should never assume that that resistor works, even if it likely does. Assuming that there won't be high voltage somewhere where there's a slim chance there will be is a bad idea.

I dont care what the build specs says , if im taking out the analog or screen on ANY 68K mac I ground the anode

Ive heard the same , post plus machine's are 'supposed' to have bleed resistors , and to back that up the only machines I ever heard the spark from were 128's and 512's.

Although 'hearing' a spark or not hearing one dont mean jack to me.

Even after i have discharged them , even after I have taken out the anode and start to remove the analog board im always on edge , focused

I assume every 68K Mac is loaded with volts regardless ......... so just discharge them all people

me no like gazillions of volts in my tiny brain
