Fixes: - C1 is too small; need more than 100k to get below 200bpm -- Clock POT is too small for film; is film needed? - Fix R25/R1 connection One socket connection is on the bottom and the MCP4922 DAC (others may work). Probably can build our own based on the front panel. Current design uses six IDC 2×8 connectors with 4 positions D 3 pin connector, https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F215079%7FY1%7Fpdf%7FEnglish%7FENG_CD_215079_Y1.pdf%7F215079-4 connector TE-Connectivity Micro-MaTch female-on-board top-entry thru-hole 12 pin connector, https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F215079%7FY1%7Fpdf%7FEnglish%7FENG_CD_215079_Y1.pdf%7F215079-4 connector TE-Connectivity Micro-MaTch female-on-board top-entry thru-hole 12 pin connector, https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F215079%7FY1%7Fpdf%7FEnglish%7FENG_CD_215079_Y1.pdf%7F215079-4 connector TE-Connectivity Micro-MaTch female-on-board top-entry thru-hole 10 pin connector, PD-30, http://www.cui.com/product/resource/pd-30.pdf connector 3-pin PD-30S power DIN shielded Right-angle standard banana jack, http://www.caltestelectronics.com/images/attachments/P315100rH_drawing.pdf DEUTSCH DT header 12 pin 3-pin CPU fan JWT A3963, 3.96mm pitch Pin head connector (http://www.jwt.com.tw/pro_pdf/A3963.pdf connector JWT A3963 pinhead 7.25mm SMT Multi-directional Spring Contact (T+R), https://cdn.harwin.com/pdfs/S1941R.pdf spring contact emi emc shield Tag-Connect programming header; http://www.tag-connect.com/Materials/TC2050-IDC-NL%20Datasheet.pdf Tag-Connect programming header pogo pins Tag-Connect programming header; http://www.tag-connect.com/Materials/TC2030-IDC-NL.pdf Tag-Connect programming header pogo pins Tag-Connect programming header; http://www.tag-connect.com/Materials/TC2070-IDC%20Datasheet.pdf Connector XT30 Horizontal PCB Female, https://www.tme.eu/en/Document/4acc913878197f8c2e30d4b8cdc47230/XT30UPB%20SPEC.pdf Connector XT30 Vertical Cable Male, https://www.tme.eu/en/Document/3cbfa5cfa544d79584972dd5234a409e/XT30U%20SPEC.pdf Connector XT30 Horizontal PCB Male, https://www.bto.pl/pdf/08988/XT60IPW-M3.pdf Connector XT60 Horizontal PCB Female, https://www.tme.eu/en/Document/4acc913878197f8c2e30d4b8cdc47230/XT30UPB%20SPEC.pdf Connector XT30 Vertical PCB Female, https://www.tme.eu/en/Document/ce4077e36b79046da520ca73227e15de/XT30PW%20SPEC.pdf Connector XT30 Horizontal PCB Male, https://www.tme.eu/en/Document/ce4077e36b79046da520ca73227e15de/XT30PW%20SPEC.pdf Connector XT30 Horizontal PCB Female, https://www.tme.eu/en/Document/9b8d0c5eb7094295f3d3112c214d3ade/XT60PW%20SPEC.pdf 3.5 mm, Stereo, Right Angle, Surface Mount, ZIF, Bottom Contact FFC/FPC, 200528-0260, 26 Circuits (https://www.molex.com/pdm_docs/sd/2005280260_sd.pdf), generated with kicad-footprint-generator JST SH series connector, B13B-ZESK-D (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator Inductor SMD 1206 https://ww2.minicircuits.com/case_style/FV1206-7.pdf SMD Type 10.7MHz Ceramic Filter https://www.murata.com/en-us/products/filter/cerafil/sfecf 6-pin 3.8 x 3.8mm SAW filter package - 1.4x1.1 mm Body; (see https://global.kyocera.com/prdct/electro/product/pdf/sf14_tdlte.pdf 0.5A, 250VAC, 50/60Hz line filter (https://filtercon.com.pl/wp-content/uploads/2019/07/Karta-katalogowa-FP-12-1.pdf Mini-Circuits Filter SMD 1206 (3216 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size from: http://www.kemet.com/Lists/ProductCatalog/Attachments/253/KEM_TC101_STD.pdf), generated with kicad-footprint-generator Molex SPOX Connector System, 53047-0410, 4 Pins (https://www.molex.com/pdm_docs/sd/026604020_sd.pdf), generated with kicad-footprint-generator JST XA series connector, B10B-EH-A (http://www.jst-mfg.com/product/pdf/eng/eEH.pdf), generated with kicad-footprint-generator Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 53748-0708, 70 Pins (http://www.molex.com/pdm_docs/sd/529910308_sd.pdf), generated with kicad-footprint-generator JST ZE series connector, 502382-1070 (http://www.molex.com/pdm_docs/sd/5023820270_sd.pdf), generated with kicad-footprint-generator JST ZE series connector, B6B-XH-A (http://www.jst-mfg.com/product/pdf/eng/eXH.pdf), generated with kicad-footprint-generator connector Molex SPOX horizontal Molex MicroClasp Wire-to-Board System, 55935-1530, 15 Pins (http://www.molex.com/pdm_docs/sd/022272021_sd.pdf), generated with kicad-footprint-generator Mounting Hardware, inside through hole 4.5mm, height 6, Wuerth electronics 9774060360 (https://katalog.we-online.de/em/datasheet/9774060360.pdf), generated with kicad-footprint-generator Inductor SMD 2512 (6332 Metric), square.
