Hi, Ian.
Many of us will tell you not to discharge the Plus' CRT: discharging it will
get you closer to the dangerous points than you'll ever be if you only touch
the logic board: on any compact, the LB is in the lowest part of the case,
and the CRT is in the upper part. Just make sure the Plus is unplugged (not
just powered off) when you're working on it. If you feel unsecure, just let
it sit unplugged for at least 24 hours before cracking it open - that should
be enough for most capacitators to discharge naturally.
If you insist on discharging the CRT, just make sure the resistor you use to
bould the tool is rated for high voltage. Such resistors are often very long
(4 inches or so) and use a square-section ceramic packaging (AFAIK).
Non-high voltage-rated resistors may be short-circuited during the discharge
and act just like a piece of wire, with a near-zero resistance. Valid
instructions on how to build and use a discharge tool can be found in many
sites arround the Internet - just use Google.

Hello.
I need to upgrade my Mac Plus's Memory to 4 Megabytes. I would feel safer if I had help from you guys.
1) Can I make my own CRT Discharge Tool?
2) How do I go about discharging the CRT?
I've read about discharging an SE/30, but I didn't know if the Plus had
a Ground Lug in the same place. I don't want to damage my Plus,
because I love it more than my 17" Flat-Panel iMac!!!!! Thats a
surprise!
If someone could answer these questions, I would greatly appreciate it.
