Philco 90 with Twin 47 Tubes in PP
#1

No RF Audio Fine

I see a difference in schematic and actual chassis. Looks Factory
Bathtub 3615AJ Supposed to contain 2 .05 caps. Parts list states .09 caps
Item 13 is shown as 733mmf and resistor 14 as 15K Item 14 is 8.5K on my chassis

Actually there is also a 56K resistor across 1-6 on Item 9 Bathtub

Looking for any changes in the 90 chassis with 47 in PP
S/N of my chassis is B83449

Anyone have updates on this chassis?
