• 10K resistor x 6 - two on the top row, four on the bottom row
• 100K resistor x 9 - six on the top row, three on the bottom row
• 47K resistor x 7 - four on the top row, three on the bottom row
• 24K resistor x 2 - one on the top row, one on the bottom row, both in the centre
• 12K resistor x 1 - bottom row, on the right
• 3K3 resistor x 1 - bottom row, on the right
• 560R resistor x 1 - bottom row, far left
Cup of tea and soldering check
When you've finished doing the resistors, stop and have a cup of tea and spend a few minutes
looking over your solder joints and making sure everything's ok so far.
Power protection diode
Install the fat black 1N4002 diode in the bottom right corner of the PCB. This protects the PCB
against reverse voltage, so be sure to check the orientation carefully.
IC sockets
All four 8-pin DIP sockets are arranged the same way around down the centre of the PCB. It helps
to solder only a couple of corner pins first, and then give the socket a check. If it's sitting correctly
and orientated the right way around, you can solder the rest of the pins. If not, it's much easier to
adjust it with only two pins soldered. Removing IC sockets from plated-through-hole PCBs like this
one is difficult and not recommended.
Regulator
The 78L05 +5V regulator REG1 is in the bottom right corner next to the power protection diode.
Be sure to line up the flat side and the curved side with the markings on the PCB. Don't mix it up
with the similar-looking transistor.
Transistor
The 2N3904 transistor TR1 is in the centre row, far left. Again, be sure to line up the flat side and
the curved side with the markings on the PCB.
Ceramic bypass capacitors
There are three 100n ceramic power supply bypass capacitors, one beside the FLANGE chip, and
two more one either side of the 5V regulator you just fitted. These are not the 100n film caps on
the bottom row far left. Don't mix them up!
Film capacitors
There are quite a few of these. Take your time.
• 100n (104, 0.1u) capacitor x 2 - bottom row, far left
• 1n (102, 0.001u) capacitor x 1 - bottom row, centre left
• 150p (150) capacitor x 2 - one on the top row, one on the bottom, both centre left
• 33n (333, 0.033u) capacitor x 1 - top row, far left
