I've got a 22BU4001, a cheaper tabletop version that was my dads in college. It was my first attempt at a electronic restoration. This was around 96-97 when I was in 8th grade. I recapped the set, but after it had a sync problem. Wouldn't lock vertical or horizontal. I was told to check the sync resistors. That was too hard then, having to disconnect one side just to test it accuratly. I moved and the TV has been in storage for 10 years. It is 3000 miles away and still awaiting those resistors.
I'm sorry my schematic for the TV is with the set. Why don't you order one from Justradios.com? Its always great to have a schematic on hand.
My dad hated the TV. It was great when it worked, but it uses a hot chassis design, and there are two metal CRT support brackets that extend to the top corners. The focus adjustment too is connected to ground and is "hot" too. He got shocked by it in the 60's and put it into storage in our basement.
So be careful after you have the TV back together and have to adjust something. be sure your not grounded!
