Question about Philips gemini CDT-05 Turntable

1 Answer

Gemini cdt-05 hybrid grounding noise

There is no grounding terminal on these decks, manual says that there is no need for one due to the turntable being grounded internally, i started off with both turntables having this bad bassline noise, i knocked the tonearm off one deck accidentaly and now that deck is fine no noise what so ever. but the other one still has the bad bassline noise, ive got a sneeking suspicion its a cable on the tonearm that is snagged of something but something to do with the tonearm ive swapped the channels round to see if it was my mixer and channel 1 *fine* channel 3 *bassproblem* swiched them over so deck 3 was playing through channel 1 and there was still the same problem.

i would just like to know if someone has got the same suspicions as me as i'm not to good with electronics and ive only just recived these decks from belgium and am a bit reluctent to open these babys up lol

poisonurhead@yahoo.com email me if anyone has a solution

    The cd function produces this weird electronic feedback giving the perception of the cd sounding like an old vinyl record with static when playing...i'm not sure if its the wires but its definitely not my mixer producing this weird output for the cd function. I had them for almost 2 years.

Well, number #1 - it's a Gemini. So, you can rest assured that the craftsmanship is not the greatest. It's hit or miss with this company.

#2, if the issue you are having is a ground issue, then perhaps the internal ground wire might have come loose, or there is some sort of interference somewhere. Do you have your turntables next to anything that draws alot of power? Such as air conditioner, or a microwave, fridge, etc? Also, connecting to the same power outlet with something that draws alot of electricity might have the same effect. Try a different power outlet. One that is not being used if possible. If you use a power strip or extension cord, try a new one.

There could be many issues which cause feedback.. the main thing is to determine what is NOT causing the problem. So, you know it's NOT your mixer. Great. Now, move on to the next step. Check your cartridges also. Try swapping them out, see if the problem follows. Many times the tonearms aren't grounded properly. There are 5 wires coming out from the tonearm - L+, L-, R+, R- and GROUND. If the ground came off during transport, or movement, this might be your problem.

Good luck!

I have two of these decks and they work well apart from when you touch the platter whilst mixing in songs, it makes a grinding noise and slows down. Please help.


You need to adjust the brake mechanism. It sounds like it needs to be tighter. Also, check to make sure the platter is on correctly.

I plugged my gemini pt-1000 turntable into the aux in the back of my stereo, but the sound is very low. Do I need a preamp?


If the amp doesn't have an imput marked phono, or deck, or turntable, the answer is yes. Search for a 'magnetic cartridge pre-amp' via google.

I'm getting a buzzing noise after hooking up my turntable that I haven't used in years. It seems to be working fine except I think I need to use a grounding wire, can you help me with this?


There should be a connection point on the turntable to connect an earth wire. Simply connect it to a metal object that is earthed, some amps have an earth terminal. Sometimes if the mains plug on the deck has an earth lead on it, it can cuase a hum. On the other hand sometimes it needs connecting.

I have an Gemini TT01 MKII turntable. The problem I have is that only one speaker audible, with a 2x RCA phono plugs(with ground cable). If I press the mono button on the amp, both speakers are...


The mono button on your amp is simply feeding one channel to both sides, so is no indication that the other channel is working. Here's what to do. With the good channel comming off your deck, swap it over so it's going in the dead channel side on your amp. If the channel does not spring into life, it's not the record deck that is faulty, but your amp. Now your thinking but it works on CD! True, but the record deck socket on the amp has another pre-amp just for that purpose only. You can track this pre-amp down by following the wires from the socket.
If on the other hand the dead channel comes to life when you swap the jacks around, then it's is the deck. The most obvious fault being the cartridge. But some decks also have a pre-amp in them.

Muffled sound


HELLO!
I don't think the problem is the actual stylus (needle), it sounds like the magnetic cartridge has become faulty in some way (it does happen). My advice is try another cartridge and stylus (borrow if you can). If the audio stays the same then it MAY be the wiring in the arm going through the plinth (deck) and these wires terminate to pins or a small pcb board in the turntable where the phono cables and arm wires are connected. There may be a bad connection inside.
Also, make sure your tonearm counterweight and anti-skate are set up properly as well as this can have an effect on audio.
I hope this helps as I have been into audio since I was a kid!

Humming noise/ feedback


your mixer should be grounded by the power cord, and the decks have a seperate ground wire which connects, usually on a screw terminal, to the mixer, which provides the ground for the decks. I would try the headshells to make sure they are tight and connected correctly also make sure the power socket on the wall is earthed properly.
