Try a different wall wart PSU with the range extender.

Some RIAA preamps make very efficient radios. The pickup arm wiring acts as an aerial and the mag cartridge provides inductance. The signals get rectified somewhere and emerge as audible interference. My record deck and NAD 3030 amp used to pull in Radio Moscow very well in the 80s.
