Clack Water Softener Circuit Board V3108 - 5 Horizontal Buttons Replacement Part for Soft Water Supply System - Perfect for Home Water Filtration & Maintenance

Fit and functioned perfectly in my AHW President water softener. My WS is over 10 years old, and I think the original transformer malfunctioned and took out the Rev-2 board. This is a Rev-9b board, and I replaced the 12Vac transformer with one from this site. Everything is working perfectly, and we will see how long they last. Shipping was very fast and earlier that originally estimated. Measured voltages of transformers,old original (12Vac, 500Ma) 17.5Vac at the board (no load) new (12Vac, 40VA) 14.5 Vac no load.
