Salas what would be the best way to make an additional output to connect a powered subwoofer to the preamp?

Either a buffer op-amp or at least 100 Ohm resistors from the main output RCAs to the subwoofer output ones. Center pin to center pin.

One UBiB per polarity (shared PSU between channels) should have 1.8R R1 in the NEG and 1.1R in the POS
