>would you happen to know where i can come by a 4x8mfd 450 v cap?
Well if the mounting bracket is still there you can fit a more modern twist lock can in to it. The original cap had a cardboard sleeve around it to isolate the cap from chassis gnd. The minus side is connected to the CT of the HV winding. You may have to slide it in thru to bottom side of the chassis as the bottom of the cap is larger than the hole in the chassis. Read up on rebuilding electrolytic caps to see how to make your own e cap for this set by gutting an old one.
Would replace the originals w/ a pair of 10mf @450v and #28 with 10mf @ 35-50v (- to the ct and + to the chassis)
>was that a 2meg replacement in place of 4meg I was reading about?
Could be. You can measure that resistor in circuit w/o taking the if transformer apart by connecting the ohm meter form the grid cap to the chassis. Have seem it way out of tolerance. By changing the value from 4 down to 2meg may make a slight difference but not a drastic improvement.
When you get a minute post a few pics of the top and bottom of the chassis. This will aid us in know whats there and what is missing.
I just need two more to finish up the second row!!!

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
