Page 9: ...he ABDX you may remember I suggested that if you wanted to run it at higher than 9v to change the voltage divider resistors here R15 and R16 to a larger value to increase the voltage output pin7 of the compressor the idea being that a larger voltage there would increase headroom and also the bias voltage of the pre emphasis filter that follows After doing some more listening tests on the 2019 vers...
