The board with the 2 knobs is to be panel mount. Now the design of the board is parallel nor perpendicular to the panel. There is no screw for the knobs (diameter 7 ....not standard) , and some components ( 100µf * 2 ) are two high for the panel to be in contact with knob/cinch input. The two connectors (power supply and signal output) have no place between the panel and the board ( 12 mm).... Only solution ....to unsolder these components and to resolder on the others side of the PCB. For the main board , a female connector will be welcome also for the power supply (2 * 26v)
