Amandarae: RE "...you can always use a tee to change the load for different values not readily available from the switch settings..." [47K, 1K, 100, 10]
What's a 'tee' and how does one use it to set the load between the four settings on the slider switch?
Oh yeah, its an RCA tee. One end is male, the two remaining are female. What you do is to use one for each channel. The male end goes to the preamp as normal. One of the female end is where the tonearm signal cable (L or R) connects to, the remaining female end is where you solder a resistor so that it will be in parallel to the load setting of the slider switch on the preamp. After that, you can calculate the effective load from the combination.
Whew! It is hard to explain it here but once you see a picture, then you will understand the concept right away. Go to AA(under Vinyl) and type "resistor loading" or such.
