STEP 2 Install 4x 100k resistors
STEP 1 Install 2x 1k resistors. (Keep the legs cut from the resistors, we need 7 for later)

STEP 3 Install 3x 14 pin DIP sockets. Notice orientation.
STEP 4 Install 6x 100n capacitors
STEP 5 Install IDC power connector. Notice orientation of center location slot.

STEP 6 Place two of the cut off resistor legs into the holes just enough to see
then poke through the other side and solder in place.
This is for the Inverted Out socket which we will connect later.
STEP 7 Do the same with second Inverted Out socket.

STEP 8 Install three more cut off resistor legs to the Switch connector holes.
STEP 9 Install main filter caps. 2x 22uf. Observe polarity. The positive is marked on the board.
STEP 10 Turn the board over to install the two Input Sockets. The Box on the silkscreen
indicates the position. These two sockets then get soldered in place.

STEP 11 Next place the remaining sockets on the main side of the board but DO NOT solder them.
We are now able to attach the front panel and secure it by adding the nuts to the Input
Sockets. Then the nuts can be added to secure the Output sockets.
Once all the nuts are fastened solder the eight ouput sockets in place.
STEP 12 Install the Invert out sockets and secure in place. The legs should line up with the socket
wires. These can now be soldered in place. It is a good idea to tin the socket pins as well
as the cut off resistor legs as the solder join should quick. Do this for both Invert out sockets.

STEP 13 Install and secure with the nut the switch. Then solder the three wires to the switch.
STEP 14 Install the two LEDS. For Green to show +Volts and Red to show -Volts install with the LEDʼs
longer leg towards the power connector.
STEP 15 Push LEDʼs into their holes.

STEP 17 Check that the -12V red stripe indicator appears at the backside of the PCB.
STEP 16 Insert the three TL074ʼs observing correct orientation.
