Do I have this right guys? Know I am describing very basic wiring, but just want to be sure since I have not replaced seleniums with diodes before. Tom Albrecht gave me the diodes and value of the new resistor to use so my B+ voltage would be correct with the 1N4007 diodes.

Video below with what I think I should do.

Thanks and I put the guidance to good use!!!

Video and photo taken 5 minutes after initial power up. All I did was bring her up slowly on the variac, tweak the horiz osc drive, ion trap, and yoke/focus coil and BINGO! My result. Guess the weeks of methodical, careful recapping and testing do pay off sometimes. Now to clean pots, tuner and adjust set with test patterns. Thanks for all the advice and guidance everyone!!!
