I agree with polar. Also if the aquadag coating gets close too the yoke it can arc to it in two circumstances: 1.) dag grounding failure (this is bad, quickly fix it if it is broke), 2.) Dag grounded, but too close to the yoke and yoke is arcing to it...This can be due to unnaturally high yoke voltage, or normal yoke voltage and insufficient insulation between things.
Some sets normally have a snap or 10 immediately after power up/power down...Snaps, after it has had a raster for 30+ sec, are where you should be concerned, and snaps that are extremely loud.

Where do those snaps come from? My Philco does that at power up and i have never figured out where its from.
Sorry for bumping in here but I had never noticed that posted before. Thanks
