Hi,
The time is almost here to get my Macintosh 512k working again. Pretty soon I'll be able to afford a replacement analog board for it.
But I have several questions, and despite having searched online and here at the forums, I haven't found answers yet (I did read that classicmac2 PDF file. The questions I have here are the few that weren't answered by it), so here we go:
Please keep in mind that I'll be wearing gloves during the entire procedure.
1)
2) In this other Mac 128k/512k PDF file I found, it says that "Replacing only power/sweep may damage new power/sweep board. Replace power/sweep board, logic board, and internal drive, then turn on Macintosh." So I gather it's saying that replacing just the analog board may damage the new one. Is this really true? Here's the PDF file, and it's on page 21:

3) This Mac has been sitting unplugged for a month; is CRT discharge necessary? If so, what's an easy way to do it if I don't have a discharge tool handy?

How can I tell what voltage it's set for?Also, verify that the machine is rated for your local line voltage.
