Could be glued on with CA or hot glue, if the PCB is used. - LEDs go in long leg down (from the front - Clock Rate - variable resist +6k between U2-8 and U2-9 - Reset Socket to U3-3 = capacitor measurement roughly 15nF (has a resistor as well - Once/Cont When in Cont mode shorts Casc Out normal to Reset In - ~27K to U3-8? No, transistors maybe activate? Outs: Clock Out - Diode from rotary pin 13? CV Out - 1K to TP5 Gate Out - 1K to U3-7 Glide section not working right, just pegging the output jacks working_height .
