Impedence and capacitance for a Supex 900 Super


I recently acquired an older Supex 900 Super in good condition. Anybody know what the impedence / capacitance is for this cartridge? Tried the web, but info on these is not easily had. Any help appreciated.

I just found a review and comments regarding a Supex 900E Super in the same magazine ( they covered 54 different cartridges at one time !!! ). This one has different loading recommendations. He also makes mention of yet ANOTHER earlier 900 Super. Which 900 do you have ? Sean

I believe this is the earlier 900 Super then. There is no "e" on the front of the cartridge - it just says Supex 900 Super.
I would procede with the above suggestions then. Sorry for the delay in getting back to you. Sean

I have this same cartridge with the original paperwork, and yes, the impedance is 3.5 ohms.
The coil resistance of my Supex 900 Super is 3.5 ohms and the recommended loading is between 20-500 ohms.
