Kit Notes (cont.)
• Flux is your friend. Use flux. Water-soluble flux is best for a clean
finish, but you have to make sure to get it all off when done, as
it can corrode the joint and some fluxes may also be capacitive.
NOTE: The potentiometers and switches are NOT sealed and cannot be
submerged; so don't wash them. You can also use no-clean flux.
• Smallest first. Solder the components in increasing order of size. Per board,
per side, not overall.
• Minimize heat exposure. Heat destroys components, and SMD are particularly
sensitive because they have less mass to distribute the heat. Flux helps with
this too.
• Use the face plate to line up the potentiometers, jacks, and LEDs, before
soldering; this is much easier than resoldering them to line them up correctly
afterward.
Assembly Order
The easiest build order is as follows:
1. All SMD, smallest first.
2. Install & solder all the headers on the Control, Jack, and Rear PCBs.
3. Install & solder the pin headers on the Main PCB - see instructions below.
4. Install & solder the potentiometers and jacks.
5. Attach the panel - see toggle switch jam nut instructions on p. 15.
Main PCB Pin Headers
The HDRMJL, HDRMJR, HDRMPL, and HDRMPR headers are used in an
atypical fashion, so pay careful attention to these parts. They engage with socket
headers on both sides so they extend through the Main PCB, and require special
care when installing and soldering. To repeat: pay close attention! Incorrect
soldering can cause the posts to not fit in the sockets, and putting them in incorrectly
is extremely difficult to repair. To install:
1. Identify each header and where it goes. There are two different headers:
the longer — HDRMPL & HDRMPR, with 0.310" head x 0.318" tail—
mate with the Control PCB (fig. 1).
