I recently bought a new turntable, the Audio-Technica AT-LP120XUSB. I wanted direct drive, decent mid-range quality (didn’t need the absolute highest spec due to my ageing & damaged hearing – I blame the school discos of the 1980s, and Roni Size gigs 😦 ) and USB built-in so I could hook up recording/streaming devices. I found an eBay seller offering new, boxed product for less than RRP and had a random “20% off eBay” voucher too so it was a no-brainer…
I really like the turntable, but the white LED “stylus target light” is absolutely dreadful – it’s cheap and nasty plastic and gives out a bright, cold white light when all the other LEDs on the turntable are red. The idea is that if it’s dark then this light helps you see the gaps between tracks so you can select the right one. They’ve obviously cost-reduced this part compared to previous versions of this model and it’s a really horrible, removable thing that plugs into a phono (RCA) socket on the turntable’s plinth. I immediately began to plot to replace it…
Shopping list: cheap phono lead (RCA) cables with metal bodied plugs that I could hack apart (thanks again to eBay) and some super-bright red LEDs (thanks Amazon).
Measuring the voltage coming out of the phono socket shows 8V when no LED is connected but it collapses to ~2.4V when the white LED is plugged in – leading me to think that there’s already a current limiting resistor in the circuit internally. A quick calc on the Electrodoc app for the superbright red LED says I need another 27R to make everything happy.
I hacked the connectors off the el-cheapo leads and drilled a hole in the side of the connector barrel. I soldered the resistor & LED onto the base of an old metal phono plug and tested it for brightness and correct height to actually light up the platter. When I was happy with the height I put the LED & plug into the barrel and filled it from the top with sugru, smoothing off the top to make a nice(-ish) finish 🙂
Really pleased with how it looks now with everything red.
The turntable sits with other pieces of analogue audio kit I’ve recently recovered from storage: my Sony MDS-JB930 minidisc deck and Technics RS-B665 tape deck. The latter now hacked so it can be remote-controlled from any web browser or from a (local) Psion Series 3a 😀 I also hooked up the Raspberry Pi to the turntable’s USB output so I can stream the audio wherever I want…

No sonic improvement here only an esthetic one, and a dubious one at that!
