DAC Output
To view the performance of the DAC by itself, move jumpers R153, R137, R156, R155 to location R136,
R135, R134, R109. The DAC can be monitored at connectors J3 and J1 from the output of the
transformers. The DAC-output-only performance is shown in
R135, R134, R109. The DAC can be monitored at connectors J3 and J1 from the output of the
