8hp Eurorack format. Aluminium panel by Clarke Robinson (C68).
This is the original version of the neuron diff rectifier, the pcb measures 34mm X 47mm and is smaller than the newest version of the pcb. Pot spacing on this pcb is 25mm c-c so these c68 panels are compatible with this pcb, while other panels (magpie, nlc) are compatible only with the newer pcbs.
