Majestic12 builds Drip Fairchild 670

[Majestic12]

I like the original frontpanel version very much but I see there is a significant difference: on the original version there are only 2 "big" knobs (Gain and Treshold) while on Tat's version there are 3 (Gain, Treshold and Ratio). How can this be applied to Drip's pcb?

The knob labeled "ratio" is just the DC threshold which in the original unit can only be accessed when removing the front panel. Tat decided to put it directly on the frontpanel.
