Corona!(couldn't remember what the word was earlier) That's what its called that it's doing, right at the CRT anode. Hissing and arcing sounds along with it!

Otherwise it looks pretty good.

Really?, I didn't know ya had to have it grounded. Yea, the spring like thing that would be on the CRT is floating above it about 1/4". Coulda sworn I seen it arc there earlier today when I was messing with the set.
Hey Electronic M, I was cleaning around it this afternoon. Didn't have glass cleaner though so I only cleaned the anode and the spring connector. That crappy looking thing around the connector that looks like electrical tape itself, looks dirty inside and slightly sticky, so I don't know how much cleaning it will help. I wonder why some sets never got HV suction cup's like this one. Then you'd rarely have to worry about shit like this.
I know that the set wouldn't have been designed around failing caps, but I didn't know if some crafty repairman could've modified it. Anyways I think I'll check into more after I get the arcing/corona/video disturbance fixed first.
Hey JR, yup, I replaced the filter caps. Some arn't the exact value as before, but I made sure to get as close as possible. I even combined a few to get close the exact specs.
Hey Eric, I cleaned it (other than the glass) and powered it up and the damn thing threw a spark out the back at a capacitor lead. I can't really move the tube out any farther. I must have had the wrap (cover) pushed to close to the anode connector.
Later today I may go back out there. Clean some more on the glass around the anode, and bend that spring piece of metal to sit on the crt. Then try it out again. Thank's guys for the help and advise so far!
