Due to my excitement when purchasing, I overlooked the seller mentioning the KUBE 200 did not have a power supply. This was totally my fault, but here I am. I have a pair of KEF 103/4 speakers with a Kube 200 but I can't use it. The speakers sound pretty good, but rather lacking in the bass.
The label on the device says 37V AC, and it has a 5 pin DIN connector. If anyone has one or suggestions on how to fabricate one, I would grateful.
