GENERAL INFORMATION
Thank you for purchasing the MOTM-485 VCF. If you have any issues concerning the
building or use of the kit, please contact us at (817) 498-3782 or by email:
[email protected].
This kit should take the average builder between 2 to 3 hours. However, please remember
this is NOT a speed contest; it is an accuracy contest. There is no rule that you have to
complete the entire kit in one day (as long as you wash the flux off!).
Successful kit building relies on having the proper tools. Here is a list of what you will need
to build your MOTM-485:
•
Soldering iron, 50W max power. Use 700ºF tip/temperature setting
•
Small amount of heatsink compound (not supplied)
•
Needle-nose or chain-nose pliers
•
Mouser lead-bending jig for the resistors
•
Diagonal cutters
•
Allen key set for securing the knobs (
1
/
16
” or 1.58mm)
•
Magnifying glass to read the markings and to inspect solder joints
•
DVM (Digital Volt Meter) to verify resistor values
•
#1 Philips screwdriver
•
Fingernail brush for washing off the organic flux
•
Old towel for blotting dry pc board
For more information of tools used and suggestions, see the MOTM FAQ and Tutorial pages

.
The 2 trimmers on the board are set “by ear”, no special test equipment needed. An
oscilloscope is handy (and fun) to look at the output waveform, seeing the effects the VCF
has using various settings.
HOW TO FOLLOW THE DIRECTIONS
Please read the entire instruction before proceeding. There may be valuable information at
the end of the instruction. Each instruction has a check box
next to it. After you
complete the instruction, check the box. This way you can keep track of where you are in
the process.
Note that this kit uses 5 different decades of 47-ohm resistors, be careful and don’t get them
swapped! Also, don’t swap the 2 trim pots (they are clearly stamped on the sides in black
ink). The 1% resistor color bands can be confusing, so always measure them with the DVM
before soldering.
VERIFY THE PARTS LIST
Verify that all of the parts are in the kit as shown on the parts list.
