RE: Forget everything I have posted for the last 5 years!

No this resistor goes from "hot" to ground to load the cartridge. There is a 47 ohm resistor with a ferrite ring around one of the leads to cut down EMF that goes from the phono input in series with a 10 ohm grid resistor. I believe I removed the ground connection inadvertently when I replaced the on- board input jacks.

This the first stage but there is no grid-ground resistor for self-biasing I assume there is a fixed bias but I haven't gotten that far along to figure it out. The other two tubes have 1 Mohm resistors.There is a 1K resistor running from the B+ to the cathode circuit (and a 22K plate resistor)for all three tubes. Trying to wrap my head around that as well.
