Over the past 19 years electrode configuration has evolved.
"Series" indicates what sort of electrodes your silverpuppy generator uses.
"Series 3": 12 gauge wire, 7" total length, bent into U shape, no brass ferrule. [Also fits "PocketPuppy" remote electrode holder]
AS of 1/1/2015 the "Silver 9" generator was modified to use these "Series 3" electrodes in order to make it easier for you to make your own electrodes from any 12 gauge silver wire you may have.
AU/NZ customers: https://colloidalsilver.com.au/ still sells electrodes
See photo to identify a 'Series 3" generator bottom.
The "Series 2" electrodes will not work.
The "PocketPuppy" was discontinued a while back.
Parts are still available on request.
If using these for "PocketPuppy" grasp the electrode near the bend and pull apart to spread the ends a little so they will be 'spring loaded' to stay in the remote electrode holder.
.9999 Fine Solid Silver, priced per pair.
Electrodes can be shipped Internationally via 1st Class mail for less [ roughly 1/2 price ] but I won't know how much less till I get the label made out.
If you want them sent 1st Class, pay what the cart charges and Type "Send 1st Class" in Order Comments...I will refund the difference.
