Philco 90 with Twin 47 Tubes in PP
#22

Chassis again SINGING STRONG

Thanks Ron for a good schematic

Thanks Mike for the IF Coil and Tom for the 2 110pf caps.

But I did end up putting the missing Item 32 Resistor in AND

Used the Original IF transformer. Had it in and out 4 times
Repaired break in Primary
The Secondary checked good with ohm meter 53 ohms but would not work in radio, Cleaned wire around rivet and soldered it. That did it

Need to do alignment , but it is playing very well . Impressed with the 2 47 Tubes. Also I am running the Console Speaker with it. May not sound as well with the 8" Speaker.

Thanks again for the input from members here. It was helpful and made things easier
