Coils measure 1.5k. 97b, shure, fits and sounds great. N70ed fit. Generic 97e went halfway in, didn't force it. N70 was really tight. Got the 97b for $10 on eBay, still available for$35. So far $7 well spent.
Possible Shure p-mounts with similar resistance:
Resistance 1550 ohms, inductance 700mH - LTP-2, M92 LT, M96 LT, M97 LT (these have similar internals electrically to the M95ED, M95HE and Era IV M97 models, such as the M97HE)
1550 ohms, 650mH - MP94E (similar electrically to the M97xE)
For some reason Shure started leaving out the specs for resistance and inductance in many user guides and brochures - the only specs they provided were for weight, tracking forces, trackability, channel separation and output voltage. So other cartridges which are probably also 1550 ohms, but for which most Shure brochures, user guides and catalogues omit any specifications for resistance and inductance, include the following cartridges:
M92E (p-mount version, not the original half-inch mount M91-based M92E model), M99E, M104E, M105E, M110HE, M111HE.
There are probably quite a few other models which I don't have information about, including OEM models.
