After reading Zilch's reply about building a charge coupled 3105, I would like to build one. Although I am an electrical powerplant senior designer (35 years) I only do cad design in the office...no field/hands-on work since high school. I can read a schematic but need all the nuts & bolts to try and build a crossover. I have my dad's soldering gun from the 50's and will give it a go. This is for a 3110(stock recapped by a JBL service center in Chicago last month)/2441(16ohm)-HL89/075(16ohm)/LE10(16ohm)-PR10 self-made center channel. Can anyone help me with a detailed schematic and bill-of-material? Thanks in advance, Kurt
