ELECTROLYTIC CAPACITORS
Values are written on the side of the capacitor. Mind their polarity (The long leg of the capacitor is the positive (+)).
Qty
Value Code Name on PCB
7 10uF 10uF C6, C10, C26, C31, C37, C38, C52
6 2.2uf 2.2uf C5, C7, C11, C16, C25, C29
1 4.7uF 4.7uF C33
REGULATORS
Be sure they are orientated correctly. The curved and flat sides of the silkscreen outline of the transistor on the PCB
must match that of the transistor’s body.
Qty
Value Name on PCB
1 LM4040 REG-1
1 AMSR-7805 5V_REG
POWER CONNECTOR
Solder the power connector at “POWER” ensuring it is facing out from the edge of the PCB.
ICs
Place the ICs in their respective sockets taking note of their orientation – the notch or dot on the top of the IC must
match that of the socket and silkscreen.
Qty
Value Name on PCB
4 TL072 IC2, IC4, IC7, IC9
1 TL074 IC8
4 AS3320 IC1, IC3, IC5, IC6
1 MCP6022 IC12
1 MCP6024 IC10
Now it’s a good moment to split the boards apart. We will consider “Control Board”
the PCB with mechanical components and “Main board” the one with the power
connector.
