BackA295bd71525185b616796bece6c52d455905c9b6 Mon Sep 17 00:00:00 2001 Subject: [PATCH 01/13] initial notes for v1 build - C1 is too small for film; is film needed? - Smaller cap (476nF?) for C1 - Ceramic 104s for C10, C14, might be fine, might introduce intermittents - Don't put R8 so close to R26 -- D36/R47 too close Testing before powering up: Clock In - U1-13 (can get at from top when assembled - Stop Switch - 10 ohms between U1-14 and U2-1 when off, more like 1M when off Single Step - 12V through 10k Ohms to U-1-14, more like 1M ohms when off Glide In - ~27K to U3-8? No, transistors maybe activate? Clock Out - 1K to U2-14 - Casc out 2x Toggle Switches, 3pin: - CV out // cv switch // Note: don't mess with them. Negative_knob_radius = knob_radius_bottom*-1; // this gets added to the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that. Consider: 1 simple on/off switch/button/knob/etc. PSU \+12V, -12V and ground needed, probably up to 1amp
