Ah!  OK.  Well if you two think it is normal, I think I will silicone the metal box in place tonight and let it dry.  I took a chance and sprayed contact cleaner on the bottom of the circuit board and some of the end tabs that had turned brown or discolored.  That cleaned them up. I dried it out, put the metal cover over it, and fired up the CC.  It booted fine.  Colors on the CRT are perfect.

I found extremely small wires on the bottom of this small circuit board in the metal box that attaches to the CRT.  They are *really small*.  I found them when I was using a hand lens.  What is that all about?  After market fix, or is that factory?

I hope my CRT is not going bad.  So far, it looks perfect.  About 6 months ago I found what was said to be a NOS CRT on ebay and bought it. It came in what looked like old factory wrapping. I double boxed it and it is going to Ecuador with me.  So if this one is going south, I can swap it out. I saw that China is selling rebuilt Sony trinitron CRTs (M23JVK12X).  I almost bought a rebuilt one, when I found the NOS one on ebay.  I have no idea if it is any good or not.

Guess I will forget about the noise after a bit.  The good news is that I can take this CC apart in the dark with one hand now.

Thanks gentleman for the good feedback.
