The 84/6Z4 is a 5 pin job. Do note that the 5Y3 and 5Y4 are not interchangeable because the filament and plate pin are wired differently. Philco sets that have the original socket for the rectifier some of the reciprocals for the pins are deleted. This means if you happen to have a 5Y3 and not a 5Y4 you can't add a few jumpers so both tubes could be used. Those sneak! This doesn't apply to this set as the socket is a replacement.
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!
