In theory I should be able to change the resistors to alter the load but I am worried that going beyond the recommended value would harm the pre amp/head amp.I've never heard of this kind of change ever harming a preamp or head amp. All you are doing is changing the value of the resistor. All associated electronic parts in this chain should have more than enough capacity.
input impedance load on a cartridge.
I am interested in purchasing an MC cartridge that prefers a 400ohm "load"from the pre amp. My head amp for MC cartridges provides 110ohms which is the highest recommendation for the unit (according to the manual). In theory I should be able to change the resistors to alter the load but I am worried that going beyond the recommended value would harm the pre amp/head amp.
Can I alter the resistors to accommodate the cartridge or should I be looking for a different cartridge (or a different head amp)?
I am particularly interested in the possibility of changing the load. The alternative cart/pre option is of secondary interest.

Thank you. Outside of doing harm to the components, would there be any detrimental effect on the sound if I were to go outside of the manufacturers recommended specs? This an Audio Research MCP-1 head amp that I am thinking about modifying. http://www.audioresearch.com/ContentsFiles/MCP1_Manual_Schem.pdf See page 3. |
In my experience Often times the best sound is not anywhere's near the manufactures recommended load. I have a herron phono stage and have preferred almost all cartridges on it with no additional low just their "infinite loading" These are cartridges that are calling for 200 ohm load in some cases that I am running at almost 47K no hard and fast rules just experiment |
