1) Resistors, diodes

Check polarity on diodes - the non-striped end goes towards the "A" on the board (for anode)
D5 and D6 are a lil beefy and might need to be pulled through with pliers. It's okay if they stick up a little

2) Disc Caps, IC Socket

It's here that I install the smaller disc capacitors and the socket for the chip, paying attention to the orientation of the socket.

3) Other Caps, Transistor

Install the electrolytic caps, being sure to pay attention to polarity. The negative end (the one with the white stripe) aligns with the white side of the circle on the board. you'll want to leave some extra lead on these so that you can bend them over as pictured on the right. Add the transistor, making sure the flat and curved sides match the printing on the board.

4) Power Socket, Vactrol, IC
Solder the power socket into place on the opposite side of the board. Flip it back over and add the vactrol in the marked footprint, making sure to align the dot on the part with the dot on the board. If  you made your own vactrol, this is where the -/cathode/short leg of the LED goes. Pop the IC into the socket, paying attention to the orientation

5) Jacks, Pots, LED

Add BUT DO NOT SOLDER the jacks and pots, making sure to place the pots at the correct locations as marked on the board. Add the LED, keeping the short leg in the cathode/square hole.

Add the faceplate, then flip it over, assuring all of these new parts are properly positioned, including sliding the LED into its hole in the faceplate

You can then solder everything into place, add nuts and knobs.
Install the nuts on the jacks first, then the pot, making sure not to bend the faceplate by overtightening. 

Turn all of the shafts all of the way counterclockwise and add the knobs, making sure to align the indicators with about the 5 o'clock position before tightening the set screws

Attach the power cable and you're good to go!
