RE: ok, so now I am really confused.....

I just checked and there is no continuity between the negative output and the case, so it must not be connected. Don't worry, I won't be messing around in there when it's hot.
The filter is my home made one I was using with the 10 volt trans. It hs a .2 ohm resistor between the + terminals of two 10k caps and the - terminals tied together, and has a dual winding common mode choke with positive going to one winding and negative to the other. The outputs of the windings go to the + and - of the filament.
Does it matter if it drops the frequency to 25kHz in this application?. It's not my design, I borrowed it from a design for an 845 filament supply that someone had posted on the asylum several years ago.
PS Just remembered the output is adjustable.... boy it is ever nice to be able to adjust the voltage to the nearest 1/100 volt by turning a screw. Now set at 10.00 vdc, if my fluke isn't lying to me.
