OBTW Here's a little something to listen to whilst your working: https://archive.org/details/TalesOfTheTexasRangers
A little service tip, don't power it up with out the spkr plugged in. It will blow the pants off of #66 which in turn will takeout the 5Y4 and maybe if your unlucky #68 read $$$$. Without #65 (the field coil part of the spkr) in the circuit there is no load presented to #66 and it will keep charging up till it surpasses it's maximum voltage rating (450v when new) and then shorts. Only bad things happen after that.

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!
