OK- so 3 feet of that is 100pf. If the cartridge spec is for 150pf the phono section should be set to 50pf.
@lewm The 12 AX7 used in a common topology typically will add about 50 pF or more to the capacitance seen by the cartridge
The cartridge specification is 100 to 200pF and the phono preamp uses 12ax7 tubes so it appears that I need go to 50pF if not zero, I left all of the capacitance switches in the off position.
Sounds a bit fuller, more impact on leading edges of notes...I think...?!
The real problem is I still do not understand what I am really doing when I change the phono preamp capacitance setting. Can anyone explain, if you have the time, or direct me to some good written material that I can review?
My brain just freezes up trying to understand the basic electrical concepts associated with this subject.
Thanks for listening,
