I'm just about ready for a first power up. Here's what I've done so far.
Power supply / sweep chassis has been full recapped, more modern fuse holder installed and huge resistive filament dropper replaced with diode + thermistor.
I used a high quality, pulse rated polypropylene cap for the horizontal yoke winding coupling cap.
Upper chassis is just about ready as well. Only challenge so far was replacing the 5AQ5 tube socket.
The original plastic socket has disintegrated but, luckily, I had a NOS drop-in replacement handy. It even had a notch to accept the tube shield
