You're very welcome @nickgreenberg.

Conceptually, for the mixer/VCA thing I was thinking about using the 20hp Praga in place of the Quad VCA and A-138s. You'd still have 8 ins and 8 outs with 4 VCAs (with boost), but it'd be more integrated and you'd add CV stereo panning and mute buttons which would get used constantly in performance. (I personally can't live without VC stereo panning.)

Similarly, the Joranalogue Mix 3 would do much of the same mixing as the A138n but you'd be adding a VCA on each mixer channel, and the LEDs and layout on the Mix 3 make it better for performance. (Perhaps you could use a WK1 or WK2 from LPZW in place of Links to free up 2hp.)
