Title
Macintosh Classic II Power Board Removal
Introduction
This guide is for the removal of the power board. That will allow for the board to be repaired or recapped as needed. Here is where it gets a bit Dangerous. Since this computer has a CRT there are some very High Voltages (27,000V) That means precautions will have to be taken. The CRT will have to be discharged before we can commence with any other work. For that we can "build" a simple discharge tool. The main thing here is, that if you are not comfortable working around high voltages, or do feel slightly worried about it, don't do it. Attached to the https://www.ifixit.com/Guide/Macintosh+Classic+II+Back+Cover+Removal/157866 guide is the Apple ESD Safety Techniocian guide. It does have the section on CRT safety in it. Read this beforehand and make sure you understand that guide. This is at your own risk and nobody else will be responsible for any injuries or damages other than yourself. It's just a disclaimer I feel I have to make. It is not as dangerous as it sounds, if it is done right.
