I am trying to find a replacement part for a hot tub that we got. It's a Cal Spa System 2000. The part number on the control is 50863. However I've been unable to find a replacement with that part number. Are there any other part numbers which could be used for Balboa SC2000?

I just went through top side control replacement in this thread http://spaforums.com/Spa-Repair/Air-Spa-Pack/Replacement-Command-Center-Series-9000-Side_5014.html .

I found that there was no direct replacement for my old controller, but the one I found fit like a glove. Check the connection to your control pack but mine was a standard config.
