Review on MOBOREST RCA Male Plug Adapter Audio Phono Gold Plated Solder 24K Gold Speaker Plugs RCA Jack Cable Connector Adapter(RCA Male-4Pack) by Alex Montgomery

Didn't work for me. The RCA ends on my vintage turntable needed replacing. I figured I could get away without soldering new wires or opening up my TT and soldering in a new RCA wire. After several attempts to try these endings I gave up. They either didn't work at all or made a loud hum. I was able to get her to work for a minute but soon passed out. I have ordered RCA cables with different types of solder and they work. YMMV depending on the application, but I don't recommend them for audio. And only for a temporary repair until a proper solder joint is made.
