I built three of them into a Frac Rack format, 6U wide panel. I brought the Scale trimmers to the front panel, did Larry Hendry's modification for the Fine controls, and adapted Paul Haneberg's high frequency adjustment to front panel trimmers, too. The wiring is dense mostly due to having to remote mount all the pots. But it fits, and best it seems to all work.
