It does not look half bad in that pic, and I've seen one of those cabinets in mint shape in person, granted the set I saw had been gutted and used as a cabinet for the set that replaced it.

had a minor set back, after pulling the chassis and replacing ONE cap a .0056 1600v bumble bee, I decided to try it out again just to be sure everything still worked and the collapsing raster was fixed. I wanted to do this before the CRT swap since the chassis is extremely easy to pull and install.

well I had a LOT of noise in the signal, huge RF noise it seemed. this was both video and audio. I noticed that when I unplugged the set the audio would clean up perfectly for a second as the caps discharged the B+.

I had a hunch it was in the HV area (the only place that can make that much noise) so I removed the Horz out tube. bingo perfect sound. I used my prob and started messing with the HV wiring and when I touched the shunt tube cap the noise went away. I pulled the shunt tube cap and the wire (thin teflon looking thing) pullled right out of the cap. A few minutes later and I had the wire reattached and the issue was gone. I ma guessing it was arcing inside the cap contained enough that I could not locate it, but arcing all the same creating the RF noise.

So with the vert rock solid now (the 1600v BB would not open the eye even at 150v) I feel comfortable with pulling the CRT and moving on.
