I was going to repost a photo of the chassis of one of mine, but it wouldn't let me repost the same photo. Here's a link to the photo:

This was taken just after the fire, and the plastic CRT bezel had been ruined. You can see the cabinet just to the Left and behind the chassis. That set was not burned, and the finish on the tamo ash wood was sturdy enough to withstand the smoke and water. It came through nicely, unlike a few other sets. Note how the Sony chassis is so huge that it dwarfs the CTC-5 console directly behind it.
I don't remember the power supply too clearly, but it has an array of LARGE power transformers and a bank of T-03 case regulators. I doubt if it's a hot chassis, but I'd have to look at the print. I think it has 5 or 6 independent supplies, each with its own transformer and rectifiers & regulation. The CVM-3000 had a 3-prong plug with the chassis at earth ground. This is the same exact chassis, but with a household 2-prong line cord.
