Hi, I have been searching for a HLW15B, PCB board for a Whirlpool luxury SPA, Model No. M3321 to work with a control panel, HLW-A-8001. I've attached a picture of the old PCB board. All the ones I have found so far are missing a SANYO transformer and are wired in a different way. Can you please help. Thank you. Wyn Rees Show More
