Why This Circuit Board?
The Right Fit, Guaranteed
Circuit boards can look nearly identical while running completely different software. We verify every board against its chip number and Balboa cross-reference before it ships, so you don't end up with a part that powers on but won't run your spa correctly.
Built for Your Model
The 600-6224 is engineered specifically for the MTS I platform, matching the original factory specifications of your 1994 Marquis spa pack.
Backed by Real Support

Frequently Asked Questions
How do I know if this is the right circuit board for my spa?
The safest way to confirm fit is by chip number, not appearance—many Marquis boards look alike but run different software. Check the white sticker near the center of your existing board for the chip number, or send us a photo along with your spa's make, model, and serial number, and we'll verify it for you.
What's the difference between the MTSICR1B, MTSICCR1A, and MTS1CCR1C chip numbers?
These represent different chip revisions used on the same 600-6224 board across production runs. All are compatible with the MTS I platform, but it's still worth confirming your specific chip number with us before ordering.
Is this a new or used part?
We carry both new and used Marquis circuit boards. Availability varies by stock, so check our online catalogue or contact us directly for current options on the 600-6224.
Do you ship internationally?
Yes. As an international e-retailer, we stock parts across multiple regional warehouses. Parts carry a suffix indicating origin—U (U.S.A.), C (Canada), E (Europe), or A (Asia)—and some parts may be duplicated across regions. Shipping costs and timelines vary depending on which warehouse fulfills your order.
What's your return policy on circuit boards?
We offer 30-day exchanges or store credit on eligible items; we don't provide refunds. Customers are responsible for return shipping, and items must be in original condition. Recycled items are final sale.
Can't Find Your Part?
Hard-to-find product? Part assistance is just an email away. Send us a message at fixmytub@gmail.com with your chip number, spa make and model, and serial number (if known), or attach a few photos of your existing board—we'll help track down the right match.

Why This Circuit Board?
The Right Fit, Guaranteed
Circuit boards can look nearly identical while running completely different software. We verify every board against its chip number and Balboa cross-reference before it ships, so you don't end up with a part that powers on but won't run your spa correctly.
Built for Your Model
The 600-6224 is engineered specifically for the MTS I platform, matching the original factory specifications of your 1994 Marquis spa pack.
Backed by Real Support

Frequently Asked Questions
How do I know if this is the right circuit board for my spa?
The safest way to confirm fit is by chip number, not appearance—many Marquis boards look alike but run different software. Check the white sticker near the center of your existing board for the chip number, or send us a photo along with your spa's make, model, and serial number, and we'll verify it for you.
What's the difference between the MTSICR1B, MTSICCR1A, and MTS1CCR1C chip numbers?
These represent different chip revisions used on the same 600-6224 board across production runs. All are compatible with the MTS I platform, but it's still worth confirming your specific chip number with us before ordering.
Is this a new or used part?
We carry both new and used Marquis circuit boards. Availability varies by stock, so check our online catalogue or contact us directly for current options on the 600-6224.
Do you ship internationally?
Yes. As an international e-retailer, we stock parts across multiple regional warehouses. Parts carry a suffix indicating origin—U (U.S.A.), C (Canada), E (Europe), or A (Asia)—and some parts may be duplicated across regions.

Frequently Asked Questions
How do I know if the 600-6219 board is right for my spa?
