The adaptors are very inexpensive. I just got a PM from Ballerina, so it looks like I can communicate that way. PM me and I'll give you the exact links for purchasing them (if I am allowed to do so)...but in the meanwhile you can probably find them yourself online at the following companies:

(1) 3" x 3" Amrex rubber pad w/ sponge insert (actually 2" x 2" contact surface with skin; 25.8 cm2) - Austinmedical
(2) pin to banana pin adaptors (to insert into the rubber pad) - Austinmedical
(3) snap to pin converters (to connect between the electrophoresor's wires and the pin to banana pin adaptor) - Balegoonline

These accessories worked for the particular stimulator I purchased. They attached to the (button?) snaps on the end of the leads that came with my stimulator. Ballerina listed sources for her purchases; I don't recall how similar they were to mine.
