Can anybody tell me four basic common loading for MC and the Odd loading some MM cartridges uses PLEASE.

It is for a high precision MM/MC head I am making for my friend Alan.
I will be posting cct here and Gerber files later for you all to play with, YES for free no money, and fun. And only 6 SMD bits Ok a lot more leaded bits.
 
Other then the standard 47k, 100 pf, I've seen people using 62k, 75k and 100k. I've also seen reference to 32k. As far as capacitance, 100-500pf, in 100 pf steps, seems to be very useful.
 
All I can find is 47K or 50K and 100p for MM, but a can recall in the 1970's some being odd values.
And the MC seem to be 10R-10K 100pF-10nF I just want four help.
 
From my experience, the three most common MC loading values are 3 ohms, 40 ohms and 100 ohms.

For instance, the Shure V15V has been suggested to run best at 62K, with capacitance in the 250-350 .
 
Thank you watch out for cct and gerber file to make you own PCB. The MC uses a complementry common base circuit but with transistors matched on the die and very low base emitter impedance thus reducing noise. And a low noise totem pole psu circiut just for fun.
