Philco Model 41-296X with 41-285 modified chassis
#26

I did the quick and dirty as instructed, disconnected fried Capacitor and removed the 84/6Z4, (out of cabinet, speaker disconnected)
plugged the set in, no pow or poof, left it plugged in for 10-15 minutes, transformer remained cool,

Then I rechecked all readings on main transformer and Audio Output transformer with DIFFERENT OHM meter, results as follows, readings on schematic are in parenthesis. ( )

Main Transformer
White - White leads - 10 Ohms (12)
Black - Black -1 Ohm (-1)
Green - Green/Yellow -120 Ohms (160)
Green - Green/Yellow -75 Ohms (150)
I guess this means the main transformer is on its way out.

Audio Output Coil
White - Black/White 130 OHMS (190)
Black - black/White - 475 OHMS (170)

guess this means the Audio Output transformer is on its way out

The Field Coil
1080 Ohms ( 1100)
So it is good, HURRAH Icon_biggrin

So I will order parts today.
