Does anyone have any recommendations on how to indentify an old cal spa. I inherited this thing from the previous owner and the the heater is no longer heating at 220V. I need to find out why, but it would be a lot easier to obtain new parts if I knew the model of my spa. I think it was made in the 80's becasue it does not have a curcuit board. It is purely analog. Does anyone have any suggestions or experience with cal spas?

Thanks,
Travis
