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?

The solution is not to be hardly consearned and just plug and play. The bottom line might be that you won't need any higher loads. If you hear the music mushy and dim with big deal of rolled off high freequencies than you might consider to replace a load resistors with larger values just by opening the box and re-soldering.
