LCR inductor hookup.
Posted: Fri Mar 01, 2013 11:37 pm
Here is the general hookup procedure for the LCR inductors.
They are wound with 2% taps so you get approximately a +-12% range from the "Bogey" value from the schematic. This tap almost always falls at the end opposite the start and I suggest starting there.
When you run the frequency sweep of the finished phono you can look for and adjust for deviations by looking at the two following sims that represent the range of taps.
The larger value choke:
The Smaller Value Choke
Finally here are the complete values for a 7320 ohm LCR unit. (no Neuman time constant)
