I was hoping for some advise (Pageup) for replacing my spa pack. The tub has no identifiers on it. It is 20+ years old but in great shape. I have had it for 11 years and it is perfect for us. I just had a new custom cover made for it. Last season it was tripping the breaker intermittently. So I shut it down until the weather warmed up. Now, the pump ran for awhile on low speed, but did nothing on high speed. Ran for about a day then tripped and wont reset. Heater and blower were working. (I never use the blower because it is soooo loud.)

Basically, I dont want to put money into this spa pack (look at the pics and you'll see why). I'm hoping you can recommend some replacement components, mainly a control box. I assume I should just replace the whole pack because of its age. I want to keep it simple. Details:

Great Lakes Spas Performer Series II (by Hercules)
Jacuzzi 7JTC-UN2 pump (3/4 hp 60Hz, 10.5/3.0 A, 3450/1725 rpm) dated 1987.
Tub has one air button: off - hi speed - blower - hi speed and blower.
I installed the timer when I bought it.
Square D GFCI breaker in the panel.

Thanks for any assistance,
Scott
