Help identifying early 60s Motorola TV?

[gdunlapsd]

Hi,

I'm hoping that someone could help identify a TV I just got; it's a black-&-white Motorola tube TV made in 1963 (so I was told anyway). Unfortunately it no longer has any label identifying the model number. I googled the numbers still present on the chasis but came up empty.

The previous owner had replaced the electrolytic caps and damper tube and did an alignment, but it does still need a little work: buzzing on white graphics, slight pincushion, blooming (I think, if I understand what "blooming" means), picture width and height change slightly over time - heat-related maybe. Nothing terrible, it's certainly watchable.

I hope I can find a schematic. I'm a newbie at this so I'd like to make sure I know what I'm doing. I got this TV to learn on and because it reminds me of my great-grandmother's TV that I used to watch as a kid. It's kind of fun to watch old black-and-white TV shows on it with my kids via Netflix and Hulu (through my Macbook Pro and RF modulator), but the TV gets really buzzy when hooked up to the computer so I'd like to fix that.

Is it still the preferred method to discharge a CRT to poke a screwdriver grounded to the chassis under the anode cap while wearing thick rubber gloves? Any other things I should do to ensure that there's no charge left in the TV before working on it?

I appreciate any help I can get!
