:Bill,
:How do you tell that they are multi-units by looking at the schematic or don't you? This is new for me. I've not run across a Resistor/Capacitor combined before...that's crazy :O) When I first saw them on the chassis I thought it looked that way but thought no that couldn't be could it.. but thanks now I will go and replace the R-13 since I only replaced C11. I think the rest are ok.
:I learn something new in every set I get into. :O)
:thanks, Bob

Philco often had resistor / capacitor combinations in their bakelite caps. I have missed more than one in a rebuld.

::Bob, you have some multi units there. For instance, C11 and R13 have same housing. One lead goes to pin 1 or 7, doesn't matter, of 6AQ5. The other lead goes to Pin 7 of the 6AT6. C11 is coupling cap. The lead wound around is just the ground lead for R13. Look at schematic. I'm not sure you need to replace it (C11/R13). I would take some measurements. If one and/or both are bad, use individual parts and follow the schematic. Likewise the other dual parts: C2/R2, C7A/C7B/R8, C9/R11, and C10/R12. Good luck.

:::::Do the schematic drawings for the negative filter cap ends denote anything different with it's forked like end to the ground symbol?

::::Bob, that's one of the symbols used for wet electrolytics. The individual values for the lugs are differentiated by the small triangle, square, and part circle symbols. These smaller symbols will be near the lugs as well on the outside with value and voltage. I don't know if that capacitor symbol was ever adopted by EIA but some did use it...yours makes point.
