Don't know that it matters. Just for the heck of it when you get it working take an electrolytic cap and connect the + side to the chassis and the - side to WW resistor/Pwr Trans junction. Value not too critical anything from 5mfd up @ 25v or higher. What should happen is a small drop in hum and an increase in the audio level. My point is that the .01 or the .015 arn't large enough to make much of a difference. The other cap on the pri of the PT just make the chassis hot with 110v ac depending on which way the power cord is plugged in to the wall.
