A challenging PCB and/or print job! See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages. Needs a _big_ knob, these are for steps only row_5 = row_4 + vertical_space/7; row_7 = row_6 + vertical_space/7; row_3 = working_increment*2 + row_1; row_4 = working_increment*3 + out_row_1; From 71d5da41172a5a79b9079ba234cbd61b0c31a525 Mon Sep 17 00:00:00 2001 From 5a420f07b2d4222c473ea8c0cf33ef6f8c915115 Mon Sep 17 00:00:00 2001 45c41b9873 Go to file From 33729ec97f6dd2ed68c4ca06088ce0b21651948d Mon Sep 17 00:00:00 2001 Subject: [PATCH] Add the label font size to 9mm and align it precisely for repeatability b11a8d3187 Change transistor footprint to inline_wide, fix DRC ground plane on only one tl074 and support Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on the right sub-panel top_row = height - v_margin; working_increment = (working_height-v_margin+thickness) / (9); // generally-useful spacing amount for vertical columns of.
