Morzh,
I sure appreciate you taking the time to help me out.
I can see how the lower value capacitor would lower the voltage. Since the lower value cap would discharge to a lower voltage before recharging, that would effectively lower the output voltage. I only have one 8MFD on hand so I'll wire it in tomorrow and check the results. I have the feeling that I'll be ordering another 8 or two 6MFD.
I've looked over the schematic and I can't see how the resistor I put in is in parallel with the field coil for the surviving original speaker. See if the following makes sense. What I see is a 3 element voltage divider. After passing thru the field coil, a B+ voltage is taken to the plates of a couple of 37 tubes, passes thru a 13kOhm resistor then on to the screen grids of the 36 & 44 tubes. Also after the field coil, the B+ goes thru the second field coil (resistor in my case) then to the chassis then the 85 ohm section of the candohm and back to the center tap of the high voltage winding. If there is no field coil or resistor, I can't predict what this would do to the biasing, but I don't think it would be good. On the other hand, if this was a one speaker set,the four part candohm would be the voltage divider and lack of a field coil would be a loss of load that would raise the voltage.

Sometimes I wonder whether the world is being run by smart people who are putting us on or by imbeciles who really mean it.
