Dear all,
I have managed to find the 3131a crossover schematic for the 4331 that I'd appreciate some help interpreting please.
My objective is to recreate this crossover (without what seems like the multi-tapped transformer L2?).
Here's the original schematic that EarlK very helpfully posted here many moons ago...
Here's my trace of the primary circuit path - Red = woofer positive, Green = tweeter positive and black is ground.....
A question: is R6 5.1 ohms?
Here's my interpretation of the 3131a in XSim (the blue highlighted resistor pair are an L-Pad block to recreate R7 in the original 3131a circuit)....
Have I worked around the tapped inductor appropriately and got the XSim version correct?
Many thanks!
