Flangelicious Construction Guide
• 470p (470) capacitor x 2 - one on the top row, one on the bottom, both in the centre
• 3n3 (332, 0.0033u) capacitor x 2 - one on the top row, one on the bottom, both in the centre
• 470n (474, 0.47u) capacitor x 3 - one in the centre row, far left, the other two on the top row
and bottom row, both right of centre.
Electrolytic capacitors
There are only three of these, but you need to watch the polarity.
• 47u capacitor - bottom row, far right
• 47u capacitor - top row, left
• 1u capacitor - bottom row, right of centre
Preset resistors (Trimmers)
There are two trimmers, the 100K Resonance trimmer (marked "100K Res") and the 10K clock
bleedthrough trimmer (marked "10K Bal"). The resonance trim is in the centre row, to the left of
the op-amps. The clock balance trimmer is top-right, next to the electric druid logo.
Second cup of tea and Power Test
Have a break. If you've got this far, you deserve it. Also, you need to be on top form for the next
part- testing the power. At this stage, you can power the board up and check the voltages with a
multimeter. There should be 9V power across pins 4 and 8 of each op-amp socket. There should be
5V power across pins 1 and pin 5 of the BBD socket and between pins 8 and 1 of the FLANGE
chip socket.
Check the soldering over one last time, since after you fit the pots, it's a lot more difficult to get to
some of the PCB.
Potentiometers
Note that the pots mount on the back
(solder-side) of the PCB!
First, break the small anti-rotation tabs off
the pots with pliers.
