I'm almost done recapping and replacing many out of spec resistors. So many in fact, there won't be many original parts left in this set!

There are also many ugly old repair attempts. The horizontal oscillator and output circuit is a good example. Several resistors have been replaced with ones of very different values. A couple capacitors have been tacked in that aren't even on the schematic. Worst of all, the HOT cathode has been shorted directly to ground bypassing the 47 ohm resistor and filter cap.


Here it is cleaned up.


I've been testing all the mica caps with a Simpson 383A Capacohmeter. So far, they're all still good.
