I HAVE A ALTA HOT TUB AND NEED A MOTHER BOARD / PCB ONLY SER ON IT ISP20GF12 FOR OR TO RUN 3KW 2 SPUMP SYSTEM RUNS AT 50 HZ. # ALL THE HELP WITH THIS WOULD BE APPRECIEATED

Hello Brian, there are many brands out there that use the name ALTA as a hot tub model. I would recommend you check the brand of electronics that you have and look for a parts supplier. Parts like that are not our specialty.
