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.
