Miscellaneous
The L1, L2 and L3 leaded ferrite beads and the B+ and B- board-mount battery contacts are
supplied with each Mini³ circuit board, so you do not have to purchase them separately. If, for
any reason, you need to replace them in the future, you may
purchase replacements elsewhere. Here are the specifics:

Notes about the ferrite beads
:
Do not substitute the ferrite beads with a different part number. These beads have been
carefully tested and selected amongst many similar products for the best performance. Using
different beads may impact the stability of the amplifier.
Assembly - Before you start
This section assumes that you have pre-drilled your front and rear panels (for the jacks, volume pot
and LEDs). If you haven't done so, see t•

Thin gauge solder, such as 0.025". Your choice of 60/40 or 63/37 tin/lead. Avoid silver solder
as it requires high heat. Lead-free solders also require higher heat and their durability is still in
question.
