Kulu, your Altura MkII is repaired and headed home! This turned out to be a QC issue with installation of the far left, Data Far knob, which frankly got worse when you tried to replace the knob yourself. 😉 We have installed a new knob yet again, and we had to jump a couple of connections where the PCB pads were damaged beyond use. So sorry for the delay. Your Altura Theremin is ready to wave!
