Ethink KL8-3, TCP8-3 & JNJ Chinese Controller & Parts

This design of KL8-3 system are no longer manufactured for new hot tubs as the manufacturer, Ethink, can no longer source the small radio board that mounted onto the processor board. Therefore they have now designed a new 2019 version with a topside that has no radio buttons on it - 'KL8-3 No Radio version'.  

Topside panel and processor board from this original system will not work with the new system.
