I’m having issues with one of my decks. When I plug it into my mixer (Vestax05ProII) it will play vinyl for about 2 minutes, then the volume gets low, and then it turns off after about 5 minutes. It isn’t sending any signal to my mixer, though it is playing on the turntable. When I take the RCA’s out and plug them back in, it starts to play again, only to slowly get low and turn off again. It doesn’t play in Serato at all.
I’ve had the RCA’s replaced on this one and it worked fine for a bit - could it be the RCA’s? Is this a common issue? Hoping I can get it solved easily and cheaply.
That’s really strange!
With reference to your description, the RCA’s are innocent. Did you check your players audio output plugged into another mixer or amplifier? Does it do the same strange volume game?
From the needle, then transformed to eletric signal via the magnets, wired through the tone arm to it’s base where than the thin cables are soldered up with the RCA cable finally… There are no passive and no active electronic components in this way which could affect souch a behavior.
Turn around your Technics and open the cover of the tone arm base on the bottom, uncomfortably you have to remove the rubber shell first - but its very easy (when reassembling, do not tighten the srews too strong, you’re in aluminum!).
You’ll will then look on the RCA cable’s ciruit board directly. Take a look at the soldering points, are they all right (mechanically) and do they shine (yes = should be okay electrically). When these points don’t fail, wiring is working. Reassemble.
Just by the way you could soak a cigarettes filter into some alcohol and then use it to clean the golden contacts of the tone arms system socket, it fits exactly. Insert the filter into the socket, spin left and right to clean, and press it (softly) a dozend times lengthwise to loosen the bouncy constructed contacts (some of them get stucked sometimes).
If the RCA plugs are okay too, you’ve verified the Technics’ complete audio ciruit.
After restoring and rejuvinating many SL1210/SL1200s in the past I concur with lauschs comments. I doubt very much your turntables are at fault, there isn’t anything I can see within the audio circuitry of the deck that could cause such a problem.
You say it is an issue with one of your decks, have you tried swopping them round into your mixer and see if the problem persists.
