1) A certain individual once said (probably on here) that the quickest, fastest way to discharge a CRT is the following (or quite like it):

a) Shut down the Mac, but don't turn it off. Leave the "You may now turn off your Macintosh." dialog open.

B) Turn the brightness to the maximum.

c) Turn off the machine.

d) Don't worry about it.

If it's been sitting for awhile, it's long ago self-discharged. It's a over-rated issue, I believe with the SE and higher (SE/30 for sure) a resistor was implanted to bleed off pretty much all of the residual voltage after shutoff.

3) If you don't know how to solder, let someone else who does work on it. Otherwise we just might get a repeat of a certain recent thread...

4) Ohm-meter at minimum, a DMM with a audible test mode is better. Helps if you have the schematics. (I only have a pinout for an SE/30)

5 and 6) Others on the board will be able to give you a knowledgeable answer.

7) It's enough. Unless you're duplicating JDW's Power SE/30 (accelerator, ethernet card, Micron Xceed, supplemental internal PSU, the lot) then even the stock fan is plenty.
