I just picked up a 1993 Cal spa model# ps-5-b. It has 2 pumps, ozonator, and is missing the blower. All is working but looks like a couple of valves have been leaking cauising some rust. Thinking about starting fresh and replacing all if it is in my budget. Any ideas on a spa pack that would fit for a reasonable prices. Any response would be grateful. Thanks.

is your system air switch controlled? I've got a solution for either air switch or digital.
