One pair of PTFE insulated, double sided terminal pins suitable for use with the mic mod audio PCB, as shown in the second image. C10 is wired to the underside of the pins.
These are a tight press-fit in the PCB holes and it may be helpful to put a fractional chamfer at the top side of the PCB, just giving a countersink bit or ~5mm a single turn by hand to remove any sharp edges.
These are not essential, just a neat and stable way of mounting the critical connections.
Alternatively, the leads of the polystyrene cap that links the two terminals can be sleeved where they pass through the PCB, or wire offcuts and sleeving can be used.
These are normally only supplied to purchasers of PCBs as part of an order, due to the cost of postage/shipping; please contact me if you need just these.
