proper loading on cartridge


Could someone tell me if the loading on the cartridge includes the ohms of the tonearm cable, interconnect, as well as the resistor in the phono stage?

Or do you just count the resistor? When the factory recommends 500 ohms, for example, should the cables be added to the resistor to get the total resistance? Or just install a 500 ohm resistor.

Thanks, Brad

Dear Brad: For a practical point, If the input value resistor of your phono stage ( no step-up transformer ) is 100 ohms and up you don't be " nuts " for the cable/connectors resistance: *** " just install a 500 ohm resistor . " ***
But if that value is, for example, 10 ohms then you have to worried about the resistance of your cable/connectors and other issues.

Forgeret about the Doug formula. The easy way to combine two or more resistor to obtain some value is: add the two or more resistance values, example: 125+100= 225 ohms, and soldered in serie. That's all.

GEE! Doug. You sure know your stuff!!Also thanks for the readable typing.I hate people who can't lay out a clear thread!!
Bfuehrer,

Raul's formula is correct for resistors in series. The formula I gave is correct for resistors in parallel. It all depends on your setup, which we know nothing about.

So don't forget either formula. Remember them both and use whichever one applies!

BTW, soldering resistors in series isn't exactly easier than inserting multiple resistors into a binding post or some similar fitting, if the phono stage or transformer provides them. Mine does and believe me, it's 1,000 times easier and faster than soldering, especially when I decide to change the resistors!
