As far as bringing it up slow, we probably all have our different procedures. But, the most important thing to remember that applies in any set is to remove your horz output tube before starting.
Myself, I start out on 20 volts, wait 10 or 15 minutes, then go up to 30, wait another 10 or 15 minutes, up to 40... so on and so forth. I feel the electrolytic cans as I continue up to make sure they aren't getting hot. They should be relatively cool, but if one seems to be getting hot, there is likely a short and it needs replacing before coninuing further. A little bit of warmth may be okay, but monitor it well. Also keep an eye out for any other signs of trouble.
Some guys take more time during this process... usually to give the lytics a better chance to re-form. In most cases, I plan on replacing them all anyway.
This Sams shows plenty of paper/wax and black-beauty caps under your chassis. It may be in your best interest to go ahead and change them out while you're waiting on your variac. The same goes for the main lytics. Being 50 years old, it would probably be better than trying to bring up the old ones slowly. Besides, it'll give ya something to do while you wait on the variac to arrive.
If you need the Sams for it, send me your address in a PM and i'll get it out to you. I have two copies for this chassis, so you're welcomed to one of them. See if you can get some numbers for the Maggies and I'll look to see if I can find those as well.
