Sutherland PhD phono stage help

Wondering if some veterans with knowledge of the PhD phono could share some advice. I know this is an older unit. My PhD has the four position gain boards for 62, 64, 66, and 68db. I would like to run at around 40 - 45 db of gain. I have the two extra gain PCB's and many resistors, but I do not know which resistors to use in the gain PCB's to get it to 40 - 45db. Any ideas?
Thanks in advance.

should get you an answer in no time from the horse’s mouth 👍
Thanks boothroyd.
I sent an email to Sutherland support and Ron Sutherland himself responded with my answer. He said to use a 100 - 200 Ohm resistor. Nice to see a guy stand behind his product.

The stock Boards had gain of 45-50-55-60db.
Perhaps if Ron could give you the values of the 4, you'd basically have yourself a stock board to play with.
