4 months ago "SMA 1/2" and "SMA 3/4" are swapped on the silkscreen, i.e. SMAs labeled as "SMA1/2" output x3 and x4 clock and vise versa. Also slide switches are mislabeled
Actually, "SMA1/2" and "SMA 3/4" labels refer to the SMA position on the front panel, not clk frequency
Following issues were discovered:
IC3 Out2 is disabled. Pin OE2 should be left floating or pulled high. Fixed by lifting the lead from the PCB

LEDs for x1/x2 selection are swapped. Fixed by cross connecting LED signals
Apart from the minor issues mentioned above, boards appear to be fully functional.
