Philco 42-345 12 mfd cap
#10

>>>it’s using the center pin as a ground connection between that point and the Bakelite block where it hooks up to the .01/.01 caps on pin 1.

No, no, no. No one said "Ground".
The center tap is THE MOST NEGATIVE point of the whole radio. If you are talking of the 12uF cap, the cap #57 that is, this is the only cap that is connected to it.
Also connected to it are: the divider's Resistor # 59 and the Grid Bias resistor #51.

The GND is the other divider's resistor #58 and the 4uF (#40A) cap's Negative; this is where the .01/.01 caps GND connection goes, if we are talking of the AC input filter #61.


Again, GND and the Centertap are NOT the samel

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
