Cartridge Loading...

My phono preamplifier has 65 dB of gain and a fixed 100 Ohm impedance load. I would like to use an MC cartridge that has a 0.5 mV output (which should be fine with 65 dB gain), but which requires an impedance load of greater than 500 Ohms.

I've heard somwehere that it is possible to have a tonearm cable custom built with internal componentry to create an impedance load of predetermined value, for a case such as this. Is that true, and if so do you know who can produce
one of these?

My suggestion is to contact the manufacturer of the preamp to see how they would recommend going about this. Chances are, they can tell you a few components within the preamp that can be easily altered to achieve whatever resistive loading that you like. If the manufacturer is out of business, try looking for someone that does modifications or repairs to that make / model of gear. Sean
