BUILD NOTES
Using SMD JFETs
The 2SK117-GR JFET is no longer available in through-hole format. This PCB uses a hybrid through-
hole/SMD outline for each JFET. An extra "G" (gate) pad is included to accommodate surface-mount
devices without the need for adapters.
SMD JFETs should be oriented as follows:
All surface-mount JFETs use the same pinout, so this configuration will fit any type that we're aware of.
However, always check the datasheet if you're uncertain—they're difficult to desolder.
Using through-hole adapters
If you're not confident in your ability to work with surface-mount parts, Aion FX offers
2SK209-GR
JFETs
(the SMD version of 2SK117-GR and 2SK184-GR) that come pre-soldered to adapters for use
in through-hole designs. These are from the same manufacturer as the ones used in the original BOSS
pedals and will perform identically.
