Finding that load resister is not hard. It will be right off the phono input @retipper has already joined this conversation and is obviously loath to give himself business by making this suggestion but, I would suggest acting as an obvious shill for Soundsmith that you send him your amp and he will be happy to make that modification and sell you some loading plugs for a very reasonable cost.
Cartridge incompatibility, Soundsmith and Luxman
I have a Soundsmith Zephyr MIMC Star cartridge that sound really amazing, but I just changed to a Luxman L-590AXII and the gain and loading is fixed.
Output/loading for cartridge: 0.4mV, recommended load resistance 470 ohm
Input sensitivity/impedence for the amp: 0.3mV, 100 ohm
The gain should be ok, but the load is way off and you can clearly hear it. The highs are rolled off and I need to crank up the volume to be acceptable level.
So here's the question... what cartridge would work in this setup? Would love to keep the Soundsmith, but I'm not going to add SUT with additional cables and all that complexity.

@audiojan , the finest 1% metal film 47K resistor costs maybe 75 cents. If you lived anywhere near me I would be happy to do it for you. I live in NH. Cost you a bottle of scotch. Lagavulin please. |
