You can safely power it up if you remove the 5Y4 tube. This prevents any hv dc being applied throughout the set. At this point you can measure the hv ac at pin 3 to pin 5 of the 5Y4 without the tube plugged in. Should see about 600vac between these pins. Your set uses octal tubes (see socket in middle of pictorial). All of the pictured are bottom views (from the underside of the chassis) not the top.

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 it!
