Ok, put that slo-blo fuse back in (that was just a brain-fart there, ignore my statements about it, I was tired that night heh), and tried it again.

That Space Command switch must be dirty or something, because I know I put it in the Manual mode to, what I assume, allow the local keypad to work. Last night it did not do anything.

Anyhow, it turned it on, and it is not blowing a fuse anymore. In fact, HV is coming on, and deflection is happening (although the set was not on long enough to warm up.)

It is squealing quite loudly. I tried to leave it on and my cats went running from the squealing. It started changing pitch after about 5 seconds and I hurried up and shut it back off again. Normal static discharge when shut off.

I went to check something, and tried it again, powered on, but now it squealing even louder.

It is not blowing any fuses now. It is staying on, and I heard audio. I never had the set on long enough to see if it produced any picture yet.

So is there anything I need to be concerned with here? I resoldered all the flyback connections. All the surrounding components on that board do check out OK when I had it out. Could it be the flyback core singing or other component? It was quite loud and kept changing loudness/pitch. Definitely does not sound good.
