Sundance® Spas Systems Transformers. The most widely used is the 6560-274. The reason we do not
sell it with the connectors is that the configuration changed several times over
the years. Where is the transformer? On many models, it was installed on the
back side of the plywood that the System is mounted to. You will see 2 "white"
molex plugs plugged into the circuit board and the lines feed out to the
transformer.
