Been on that Dynasty site with serial number a few times, great resource... but they are pricey (for spa pack at least). Found new spa pack for $330 which is a replacement for the one that’s currently in there (part number is a direct replacement for the current one I have... guess it’s been updated a little). We’ll see about shipping speed; I am going to call the company later today and make sure they have in stock. Another online retailer claims they have in stock, so can go through that route if it’s held up too long.
