Thanks Lime Twig.
Here it is in a not-complete, but usable state while I perfect the Wet/Dry section. (I think I'm going to end up with a stepped 4-gang potentiometer in there to get the curve just right.) I'll probably re-use the Booth output circuitry as a driver for the effects unit and re-sum with an Edcor summing transformer.
Upgraded many parts, simplified the cueing section and actually eliminated a channel.
Other plans for upgrades in the very near future include:
* Install vintage UREI 1620 balancing/output transformers (it is currently transformerless). I'm hoping this will give the mixer just a touch of what I call the "American Sound".
* Install vintage milspec Torotel input transformers and eliminate the input DC filter capacitors.
* Linear Power Supply in separate case.
