Thanks to all for guidance on phono pre. Jolida JD9A a couple of questions

Posted by KWILLIS (A) on November 17, 2006 at 11:20:56

OK. I finally got the point. I bought a better phono pre amp, a Jolida JD9A. I just got it in today and I have a couple of questions. First, how do you distinguish between a JD9 and JD9A? The unit has JD9 on the front. The owner's manual does not say JD9A in it anywhere. The picture on the Jolida web site calls the unit a JD9A but the picture shows JD9 (see link). I have a Dynavector DV20XH. I think I am to set the dip switches as follows: switch 3 mc2 (high impedance) ON, switch 4 47000 Ohm ON. There are 4 other switches that appear to be for setting capacitance; the values are 47 pico farad, 100 pico farad, 150 pico farad, and 220 pico farad. Can anyone give me an idea of how to set these and / or what they do? The manual does not explain that at all.

Once again....many thanks to all who took the time to comment on my request; and give guidance where it was sorely needed. Thanks even to those who, although I readily admitted my own ignorance, stubborness, and downright stupidity, saw fit to rub my nose in it some more anyway. Thankfully they were the exception rather than the rule. But, some lessons are harder to take than others. And I will concede that maybe I'm being a bit over sensitive.

I'll post my opinions after I've listened to it a bit.
