    Yeah I think I'm going to just replace most of the caps. I did pop out the 470uf and 4.7uf at C83 and C82 respectively (the service manual says to check there first if no power). They do seem to...

    When I plugged it in, it made this awful whine noise and didn't light up (I didn't dare leave it plugged in very long). I've only ever heard that noise before.. after I broke another CRT by accident...

    Dang.

    I did figure out a way using JB weld to reattach the screen to its mounts. But when I looked more closely at the CRT neck, I could see what looked like possible little cracks in the very...

    Thanks Mike.

    That's interesting.. so 301 would be January 1983. So 301000089 would imply this is the 89th unit (since there weren't any earlier than 1983)? That'd be pretty cool.

    The NiCD has risen to 3.3V now. I'm surprised I'm getting anything.
