Slow , steady , methodical!
As suggested above, disable what is not needed and see what happens.

After reading the VA-48 manual, its a better way to check alignment than doing the factory thing: marker and sweep gen with need for clamping AGC, etc.
You will probably tinker some more with that set over time, it looks like you have great equipment, that did not exist in the 60s.
For about 7 years now and thanks to the internet leading me to awesome folks like this forum has, I have tripled my number of projects and just now I start to recall the persistence needed. I feel fortunate to be the first one in other than tube-swappers, to see these sets as they came from the factory. To be sure, I have been able to repair super-dogs that showed evidence of long bench hours..
Each time I populate these with tubes and fire them up, my intent is to reassemble the TV again and if not 100% ready for home or sale (?), trade it to another collector. That's what we do to keep each other sharp
Out to the barn I walked, thru 8 inches of snow this morning to get some tubes from about 6 caddies, and sorted vegetable flats. Caddies are all full of boxed tubes but often used/tested are found in boxes. But I did get a new 6EA8 for the tuner, several 6BK4s. I try to pick RCA tubes if possible with dates close to 62-35, date chassis is stamped.
I just fired up my CTC12 starting at 70 then up to 95 volts AC, got some RF on the 6DQ5 cap evidenced buy my neon stick, no hot stuff or smoke and good sound.
pics up soon
