Philco 90. Early Production 45-45 Push Pull
#1

Just putting the finishing touches on this one. 

The final choke point to wide open throttle output was that miserable Normal-Max switch which was scratchy and dodgey.

I figured out "Max"was an @ 70 ohm circuit and "Normal" was 0 ohms. Switching to "Max" yields the high gain signal. I looped a lead on the right side of the switch ( looking at the chassis upside down) and was rewarded with clean, clear signal up and down the dial. No need for the switch.

This is a good performer and the cosmetics are 90-plus. It's a gift for my older brother.
