I decided to start recapping the sweep board and cleanup the HV cage.
 It's fairly easy to work on the PCB in place. I just hard to untwist a few tabs holding the pots down and unwrap a couple wires.  It's even easier if you go a little farther and dismantle the HV cage.  That also gave me a chance to remove the corrosion. Here it is ready for reassembly.  I noticed this set specifies a 1J3 HV rectifier although I found a 1B3 installed. The only difference between the two tubes I could find in the specs is the plate drop. It's a couple 100 volts more in the 1J3. It makes me wonder why the 1J3/1K3 even exists. Why not just always use the 1B3/1G3
