Dual Master Buss Compressor

The stereo compressor is two mono compressor circuits with some
extras designed for mastering and buss compression duties. The power supply
has separate high voltage and heater regulation to minimize cross talk.
There is a dry signal additive knob and a constant volume wet/dry mix control,
as well as an output attenuator.
All controls are precision stepped switches. Fine gain trimmers are provided
on the front panel for small stereo gain differences over time due to tube wear.
Want a pure tube and transformer audio path?
There is a switch for that. For those times when you don’t need the solid state
wet/dry mixing features, you can simply switch it out of the audio path.
The passive output attenuator remains functional.
