Top 20 Gemini XL-500 Turntable Questions & Answers

Look at the cartridge make and model number fitted. Put that into Google and the type of stylus needed will show up.

Hi, slip the ground cable in the side of the rca connection to the device without earth point.It makes no difference if it goes in the left or right jacks. [email protected]

Maybe this will be of help?

See if you can attach the ground wire to a point on the chassis of the device you are connecting it to.

No! The amp must have a magnetic cartridge pre-amp to increase the sound level. If it has one it will say "phono" on the inputs on the back and have a "turntable" - or "Phono" selector switch. If it doesn't have one (many new surround amps don't) you won't be able to play it properly untill you get a "magnetic cartridge pre-amp". This will make the signal loud enough to be used on a normal aux imput of the Sony.

Try this company but remove the <remove> bit from the link?

HELLO
This should be straightforward. Take off the slipmat and lift off the turntable (platter) and you'll see there is a rim on the underside of the platter this is where the belt goes.
Put the belt round that rim and you'll notice a couple of holes in the platter itself. Hold the belt through one of these holes and put it back on the tunrntable while taking notice of the motor position on the deck.
When the platter is in place (still hold belt) and move the platter to the position of the motor pulley and slip it on. Manually turn the deck once or twice to make sure it is in place - DONE! Replace the slipmat.
ENJOY! (:-)

Typically, one would run a single wire, 18 or 20 gauge will work, from the turntable motor housing to the amp chassis. I know the older amps have a ground screw on them,, but any chassis screw will work.

if there is a slot for a power cord on the turntables them selves then yes you need the power cords

on top of the pitch control there is a small hole, in this hole you can use a small screw driver  and turn it left and right to free any dirt inside this is the master pitch control

OK found the solution - need to connect to preamp before my comp.

No, the issue is either with the RCA cables or the tonearm. You might also want to check your cartridge and headshell connection. Make sure the contacts are nice and clean, and securely on the headshell. Have you tried swapping out your turntables? Take the left turntable, and put it on the right channel's input, and vice-versa? This will tell help isolate the issue. If the problem just moves, then we know it's not your mixer. If the problem remains on the same side, then you know there is something wrong with your mixer.

If the problem moves, then you can safely say it's your turntable with the issue. The STR8-30's aren't the greatest quality, so it's also possible that you have a faulty tonearm or RCA cables.

Hope this helps.

aaaaaaaaand...........what's your point?

You will need a phono preamp. Ipods, radios and cd players all give out a LINE level signal..which means you can plug headphones or speakers, adjust volume and be set. A turntable needs a phono preamp. Usually a dj mixer or stereo receiver with a phono input is all that is needed. A simple phono pre amp is like $20 from radio shack.

keep me posted.

Clean Your Turntable with a microfibre cloth. Power off the turntable and unplug it for safety. Access the turntable's platter by lifting it off. Inspect the belt. If it's loose or damaged, consider replacing it. Amazon should have the belt replacements. If Your Record Player Spins Too Slow, Here's How to Fix It in 3 Steps - All For Turntables

It is strange that both won't open, something common to both, power supply to them? https://www.google.com/search?q=gemini+cdx+602+drawers+won%27t+open ..

measuring that voltage wont tell you a lot of information. You need to see signals in an audio circuit and those transistors could be MOSFET and or they cannot be tested while in circuit.

Much depends on the noise and where it is originating. The deck doesn't seem well thought of and it is unlikely the manufacturer has a spare parts service - unless you have the skills needed to locate and rectify the "noise", which could be electrical, electronic or mechanical, and otherwise restore the deck it would seem advisable to replace it.
