Hi Wayne,
Several questions:
1) I don't understand how to measure the noise on my Paramours. I use the AC portion of my VOM, and hook the black lead to a ground (like T14), and the red lead to what??? And, what should I be seeing? What kind of reading is too much, etc. This is to be done with the Paramour powered up and the RCA jack shorted out?
2) Also, some clarification of the "...0.022 mF caps across the diodes". Now, I'm not sure what you mean by "across".
Do you mean for each of the two diodes a cap should attach to the ends of each diode? Or, do you mean a 0.022 cap will jump from one diode to the other. Sorry that I don't understand this basic concept. Not your writing. My inexperience.
3) As for going with larger value caps in the power supply section. How much larger? When you do this, does it change the B+ value the audio section sees? Same thing when you add a choke? How do you select the value for the choke?
I know, I know...start calculating, right? (E, I, and R) 
That's what I was afraid you were going to say...
Thanks,
Mark
