Terry, the reason I asked that question is that it would be easy to hook the field coil between the 8 and 16uf cap rather than between the 8uf caps.  I have no idea if you would get hum that way.  On two of my 610's these caps were in different positions than shown in the manual (and these  were unrestored  originals).  I restuffed them one at a time, put them into the radio and was really  confused when tracing the wiring.  Here's the cap placement that was on two of my radios (I need to check the third).  Parts 54 and 41 were reversed.
