Philco 90 with Twin 47 Tubes in PP
#8

No, no, no, you have to go with the right schematic for the right chassis.

The correct schematic for Bob's chassis is near the end of the link he posted...or may be seen on the link you posted earlier, Mike.

The late version 90 is a very different animal from the earlier 90s which had separate oscillator tubes. The late version (2-47) 90 combines first detector and oscillator functions in a single tube...just like the infamous model 89 and others I listed previously.
