I am working on a Philco 90. Capacitor 28 has three capacitors, .5 ufd, .25 ufd, and .25 ufd. The schematic does not give the values and I would like to know which one of the capacitor symbols is the .5 ufd capacitor on the schematic?
Thank you,

There are several versions of the 90. Ron has annotated these schematics, does this help?
Early Version (2 45tubes)
Middle version (1 47tube)
Late version (2 47tubes)
