Changes and notes
Before you start building your new microphone please carefully read this
building instructions.
Attention: V-414 is not DIY beginners project. This is due to the fact that the
circuit is very complex and boards designed with very limited space in the
microphone body in mind. Good soldering experience and soldering stations
with very fine soldering tip is required for successful completion of the
construction. If you do not have this, please delegate the construction to a
more experienced technician with proper equipment. We are not responsible
for malfunctioning construction or injuries associated with improper
assembly of our kits.
V-414 BUILDING INSTRUCTIONS

VAMISOUND V-414 set includes main parts board, transformer board, switch board, three switches and four
teflon pins.
Start fitting the transformer board with resistors and two inductors.

Continue with soldering two red film capacitors, two blue ceramic capacitors, three electrolytic capacitors and
two transistors.
Next up is the main parts board with point to point HiZ section. Soldering the HiZ section might seem a bit more
challenging but with a little patience you can do it.

As you can see in the picture, on the gate leg of the fet transistor there are three ceramic capacitors, one
resistor and also two film capacitors soldered „in the air“. There are also four teflon pins.

After completing the HiZ section clean the entire area with isopropyl alcohol. Use cotton cleaning sticks. Make
sure there is no flux residue or other contaminants on the joints.

After cleaning, fit the rest of the board with resistors, capacitors and last transistor.

Next in line is switch board. Solder the three switches into place. On the 4 position pattern switch use pliers to
snap one pin protruding from the metal body to fit the switch board. Try to insert this switch into the pads on
the board before soldering and it will be immediately clear.
Use the remaining legs of the resistors/capacitors and solder them on the switch pcb as follows:
Make sure you solder the resistor legs to the correct side of the board.

Carefully but thoroughly clean all plates with isopropyl alcohol. Pay particular attention to the switches to
prevent isopropyl alcohol from entering them.
Everything is now thoroughly cleaned so we can move on to more pleasant things.
Installing the famous Moby’s transformer is always a fantastic experience. Insert the transformer into the
cutout of the board and carefully pull its cables through to the other side of the board.
Do this carefully as the cables are very delicate and can easily break.
