At long last, a Chromacolor II!

You could be hearing some corona discharge but I wouldn't go sniffing for it!! Make sure the HV lead is clean/not sticky along with the anode connection on the tube. As mentioned elsewhere, if the sticky goo around the anode has run down towards the yoke, slide it back/off if necessary and clean it all up. The HV block could be gooey too..or leaky.

And while you're at it, make sure all the CRT ground straps are secure too! You can troubleshoot this with a lack of equipment. Just be sure to be safe about discharging the anode and during your cleaning process continue to keep it discharged. Oftentimes some residual voltage will exist. The anode wire should be ok but check it out good too. There may be a screw that fastens the clip to the cup that also serves as the wire connection too. Easy to check.

That's the whole reason for my hesitance. I have never discharged one of these things, and before suggesting I use a screwdriver to discharge it... No.

This is where the one hand behind your back rule applies!!

You can use a bleed-down resistor as mentioned, or I have a long, skinny screwdriver that I attach my 'gator lead to going to chassis ground. Sometimes with a bleeder resistor in there you'll not hear that you've made contact. Discharging electroytic caps, by all means use a bleeder (with a meter to monitor- lot'sa current). I can understand your hesitance! Just slide that 'driver under the cup and listen for the "snap". You'll be okay!

If you're still hesitant (understandable!) then apply the buddy system and have someone present with you. Once I got over that initial fear myself then I realized that it's not a big a deal..really!!

But you've got to get that plastic/gooey flap pulled up out of your way first so you can see what you're doing.

And kudos to you about wanting to be safe. We're limited to ways of discharging CRT's. And, if there's still a TV guy in your area (or one of us) don't hesitate to have him show you.
