Optional) - Casc Out normal to TP10, optional 2x Toggle Switches, 3pin: 11 Toggle Switches, 2pin: - reset Pots, 3-pin: Glide attenuator (B10k) (join two left pins from below - Glide, manual (A100k) (two left pins, from below) - Clock rate goes down when resistance goes up, opposite to expectation. 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 From 812d609d12a788e600a582b2b6e7494f6d2b0728 Mon Sep 17 00:00:00 2001 Subject: [PATCH] checkpoint after roughing out middle PCB Move LED resistors next to a separate dangling reverb tank?
