Philips turntable identity
Hello,
I recently got a Philips international hi fi turntable but don't know it's model number, can anyone help identify which one it is. Also can someone tell me if this needs an amplifier to use it, the speaker wire was cut and I wonder should there be 2 speaker leads. I have photos attached to view. |

Re: philips turntable identity
This turntable needs to be connected to an amplifier which has an input for a ceramic cartridge, via the dual screened cable which has been cut. The other cable is for the mains supply.

Re: Philips turntable identity
Pretty much any stereo amplifier from before about 1990 will work. If it doesn't have specific inputs for a ceramic cartridge just use the aux in ones. Don't forget you'll need a pair of suitable speakers too!

Re: Philips turntable identity
I have the autochanger version of this TT - it's a decent quality deck. You will need to get inside to replace the mains cable and the screened cable to connect to an amp. Hopefully the cables have been chopped for convenience or because the seller wants no responsibility for whatever might (or might not) be wrong with it! That's common enough. It's straightforward wiring but how confident do you feel about that? If 'not very' take it one step at a time and keep us posted.

Re: Philips turntable identity
The connections look like a twin screened audio cable and a mains cable. The absence of any sound controls shows that this turntable was definitely meant for use with a separate amplifier. You will have to open it up carefully, and connect new cables to where the old ones went.
The cartridge could be ceramic or magnetic. If magnetic, each channel should read just a few hundred ohms with a digital meter (anything that doesn't read open circuit on the 200kΩ range is fine) and the readings should be about the same on both channels. If ceramic, each channel should read open circuit even on the 2MΩ range, but that will not tell you whether or not the cartridge is actually any good. Many amplifiers made after about 1980 will have only magnetic phono inputs (magnetic cartridges having taken over from ceramic ones by then), and many made after about 1995 will have no phono inputs at all (CDs having taken over from records by then). A ceramic cartridge might not work well into anything but a proper ceramic phono input (or a homebrew preamp). A magnetic phono input will have too much gain and have RIAA equalisation applied (which a ceramic cartridge does all by itself, mechanically rather than electrically, anyway), resulting in severe (and not speaker-friendly) distortion. A "normal" (tape, tuner, CD, aux .....) input won't have RIAA equalisation; but it may have too low an impedance for a ceramic cartridge, resulting in a "thin" sound. It's to be hoped that the cartridge is fine -- and preferrably a magnetic one, because that will make everything else so much easier for you -- as it's a Philips and therefore not easily substituted with anything else.

Re: Philips turntable identity
That's a plug in stereo ceramic cartridge fitted. A very nice semi-automatic deck, although the platter mat does not look original. There should be a white sticker under the platter to identify it. The model number will start with a "GA".

Re: Philips turntable identity
The cartridge isn't obviously a turnover type, so could indeed be magnetic.

Re: Philips turntable identity
But in this instance, it's one of those Philips, plug-in ceramics

Re: Philips turntable identity
There should be a sticker with the model number etc. printed on it. I suspect it will be visible if you remove the platter.

Re: Philips turntable identity
It would be worth having a photo of the cartridge taken from the end just to check as Philips certainly produced plug-in magnetic cartridges and the arm looks similar to those that Philips used with their later magnetic cartridges. Of course the later arms and cartridges had a more conventional headshell with the standard screw fitting for the cartridge.

It's a 22GA217 with a GP233 ceramic cartridge: https://www.radiomuseum.org/r/philip...722_ga_21.html
