In Sams, the convergence board & procedure for your set looks similar to my RCA CTC-11. You don't need fancy equipment to adjust convergence. It is basically looking at the screen and turning the little adjusters. No doubt you'll have an easier time than I did with that CTC-11:

One thing you'll need is a test pattern generator. If you try to adjust convergence while watching live TV or looking at a still picture of Howdy Doody, you'll probably make it worse. In the past I have referred people to a web page that lets you make a test pattern DVD. When I checked that site today, my browser gave me an alert, so nix on that for the moment. You can find used pattern generators pretty cheap at swap meets or on eBay.
For convergence, you use a black and white pattern. I use a crosshatch most of the time.
In terms of order, convergence is just about the last thing you address. Prior to that, you need to have good "black and white" geometry (height, linearity, etc.). You also need to degauss, adjust purity and grayscale, and so on.
Perhaps you lead a charmed life and those old electrolytics will last forever. If it were my set, I'd replace 'em and sleep better at night.
