Hi, Yes on the RCA cables, there is a corresponding option on the front specifically for the turntable. Will take your word for it regarding the pins. My only point was that it is powered by the receiver. Karen On Wed, 2 Jul 2025, Scott Allen wrote:
Although the plug I have connects to a port I believe is labeled phono on the back
If it is labeled "phono" it would only be because it's for connecting to a phonograph. "Phono" plugs are generally understood to be another name for RCA plugs. The PS-LX295 turntable also has two phono plugs (RCA plugs) on cables that feed the audio output to the receiver.
it also seems? to have more than three pins, even if indeed rectangular.
If your turntable is a model PS-LX295 or PS-LX285, the rectangular power connector would definitely only have 3 pins (and only the two outside pins are actually used).
