Philco 80 has me stumped
#8

Hello again,
I had a chance to look at the values of the resistors around the type 36 second detector.
The 1 meg on the screen grid is 1.9 meg ohms instead of the 1 meg ohm standard value.
The 10K ohm resistor on the plate measures 13 K ohms.
the .24 meg ohm resistor connected to the 10K ohm plate resistor measures .61 meg ohms.
The .49 Meg ohm resistor on the grid 1 of the type 42 is open.
The second detector grid cap measures 4 meg vice the suggested 5 meg ohm value.
The tuning capacitor shell measures a very steady 200 ohms to ground.
And last and this is strange that I did catch it before. Someone in the past moved the antenna input to the wiper arm of the input sensitivity control and coil connection is now on the top of the sensitivity control, The control does measure 20K ohms.

I have some work to do on this beast from an attic in New Jersey.
