Table of Contents |
This page has become really long, so here's a table of contents that we hope will make it easier to traverse: Parts - presents a Bill of Materials and notes about it Panel - presents the alteration to the Synth Tech panel Construction Phase 1 - Resistors, Capacitors, IC Sockets, Power Parts, MTA headers Construction Phase 2 - Trimmers, Panel connections |
Parts |
Will and I have developed a parts-list / bill-of-materials in the form of an XL spreadsheet based on the parts list in the 420 User Guide. Click here to download the XL spreadsheet (apx. 350K).

Panel |
Because we're including the Tellun 800-DB, we needed to modify the Synth Tech panel to include two LEDs - one green - one yellow - which will serve as indicators for the action of the clipper and the progress of the envelope. So just like we did before, we drilled the two LED holes in the panel we got from Paul. For details, go to the MOTM-800 Page, here. |
Construction - DB-800 |
We built this back in Aught 7 when we built the other four 800ds. Click here.

Construction Phase 1 All the stuff in Phase 1 gets soldered using "Organic" Solder. At every break in the action, we wash the board off to get rid of the flux. |
Cut Traces We decided to cut these traces on the bottom of the Main PCB like we did last time to accommodate the DB. Resistors
As usual with us, whereas we are vigilant about orienting all the resistors, caps, etc. consistently so their values can be read easily (in case we need to trouble-shoot them later), we oriented the resistors with the "Tolerance" stripe on the left (relative to the text on the pcb). You might want to do it the opposite way. (For the table of resistor value markings click here.) Capacitors Power Header, Ferrite Beads, IC Plugs, Semiconductors We decided to use Jacks for our ICs - optional. |
Construction Phase 2 |
Pots |
Wires We fit the pots into the panel. Looks to us like the 3 Coax and one twisted triple can be around 4-1/2in long: |
MT Plugs Here's how the wires go into the MTA plugs The jumper and wires on the back of the PCB The gate wires |
Trigger, Coax, ICs |
Jacks |
