A pair of 1G resistors suitable for condenser capsule bias feed and the JFET bias feed on my mic mod boards.
The second photo show where they are installed on the audio PCB, with the outer ends in PCB pads and the inner ends on the insulated pins.
Note that the majority of multimeters are unable to measure the value of these resistors, it's simply beyond the typical working range.
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.
