Hi Travis... welcome to our group!
Before bringing up your set slow, take a quick look at your flyback transformer to see if you have any burn marks or lots of melted wax. Those RCA flybacks are not the greatest at times. If it looks okay, then you could proceed with the soft start.
Make sure to remove the horz output tube before bringing it up slow. Monitor the feel of your electrolytics to make sure none of them are getting hot as you bring up the juice. They should remain relatively cool... or slighty warm at the most. If you feel a can getting warm or hot... say by the time you get up to half power, you might need to replace the electrolytic before continuing further.
If all goes well, you should start to get some audio out of the speaker by the time you get to 80 volts... give or take. If you get any 60 cycle hum out of the speaker, you'll need to go change lytics.
After getting it up to full power and letting it run for a while, continue monitoring lytics and for any other sign of trouble. If all seems well, then you could power it down and put your HO tube back in to see what you get on the screen. Check that flyback again also after it has ran a little while.
If you have the time, it might be wise to yank the chassis first to take a quick look underneath so you can see if there were any apparent failures such as blown caps. If you see alot of those "black beauty" caps, it would be wise to get those swaped out for new caps. Old black beauties always seem to cause problems. While you have the chassis out, it would be good to spray some contact cleaner into the various controls.
My cTC11 had a shorted rectifier diode in it when I brought it up slow. Every time I got it up to 35 volts on the variac, it tripped the breaker. I'm glad the breaker actually worked... as many times they do not. If it turns out that you only get lit filaments and nothing else, the reset button may be tripped.
It will be a good assumption that some lytics will need changing, if not all of them. Although it might still power up pretty well.
Good luck!
