112 schematic discrepancy?
#1

I am rebuilding the filter capacitor on my 112 chassis...and I have run into a problem with the schematic and diagrams not agreeing. I have compared the schematics in the Philco 28-36 book, with the Service Bulletin, with Raf Bintliff's book. The diagram of the internals of the capacitor block don't jive with the schematic. Particulars is the capacitors between lug 8-9, 9-3, and 10-3. The diagram says a 0.15uF goes between 8-9, a 2uF goes between 9-3, and a 2uF goes between 10-3. But the schematic says that a capacitor goes between lug 8-3, lug 10-9, and 9-3.

Does anyone have knowledge of which is right?
