Good time to find one. Doesn't have to be anything fancy but it allow us to inject a signal and hear what stages are working. You can go thru and measure the pin voltages on all the tubes (5Y4 is ok) and see if there are any anomalies.
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!
