MK106 Metronome - No speed control


I just built the metronome and am very excited to use it! However, adjusting the beats/min dial is ineffective and the volume dial is basically on/off. What steps should I take to troubleshoot this? This is my first build so I’m not sure how to diagnose/solve issues.

Based on the symptoms, it seems the potentiometers RV2 and RV3 are swapped…
Should be:
RV2 : 1M ohm (BEATS/MIN)
RV3 : 100 ohm (VOLUME)

Ah okay, so the pots in RV2 and RV3 are different values despite being the same size? It definitely makes sense that that would be the source of the error. I assumed the smaller one was the smaller value and the larger two were the same.
