OK in that case we must start at the beginning...
first the explanations.
The simplest cartridges (the bit on the end of the arm of the turntable, which turns the movement of the needle into sound) are what are known generically as Moving Magnet cartridges. (Strictly speaking some of them are moving iron, but that is getting technical...)
Moving magnet cartridges put out only around 5mV - and a normal RCA input require between 50 and 100 times that at around 250 to 500mV.
Also because of limitations in the vinyl medium, records are recorded with the bass frequencies reduced and the high frequencies increased - so when playing them back you need to lower the bass and raise the highs in precisely the same proportions used when recording the LP... This is known as the RIAA Equalisation standard (Recording Industry Association of America - there are other international standards but they are the same - or very close to it - and this is the most common term used for it).
So you need to take the signal from the cartridge, amplify it, equalise it, and then feed it to your amplifier - where you can control the volume and in turn power your speakers.
The in between step before your amplifier is called the Phono Stage, or the Phono Pre-amp....
Some amplifiers have this built in - in which case you will see a set of RCA inputs at the back labelled "Phono" - many current amplifiers do not have this as most people no longer own turntables!
Any amplifier or receiver sold before 1985 is pretty much guaranteed to have a phono stage in it.
Often the best way to get started is to find a nice old amplifier that someone is throwing out (it is 30 years old... it must be junk.... if you pay me a few eu. I will Help you by carrying it away for you...).
Of course then you will need speakers.... same thing - the good speakers of 30 or 40 years ago are still good speakers today.... as long as they have not been mistreated or suffered from specific aging problems ... (speaker surrounds - rubber - can deteriorate with age, capacitors can also deteriorate).
So what you need to start looking at is how to setup a new(/old) music system.
It will need to have speakers, an integrated amplifier or receiver, and a turntable....
Sometimes the best way to start is with something like this:http://cgi.befr.ebay.be/Chaine-Hifi-/12 ... 500wt_1156
orhttp://cgi.befr.ebay.be/Chaine-HIFI-JVC ... 500wt_1156
(but you still need speakers)
orhttp://cgi.befr.ebay.be/Teac-Reference- ... 500wt_1156
(very nice compact system - but you still need speakers and turntable - nice little amp though)
orhttp://cgi.befr.ebay.be/TOP-HIFI-SYSTEM ... 195wt_1139
No magic here - everything is basic, but the system is modular - you can replace parts of it when you can afford to.... and it does include everything - the amplifier has a phono input for the turntable....
Most of the previous advice was based on us assuming that you already have a "HiFi System"....
Given that this is not the case... we need to step back, and readjust expectations - with only 150eu to spend on an entire system.... something much more basic is required.
Another alternative could be to skip the speakers and use headphones.... - that depends on how you like to listen!
You need to keep an eye on ebay or whatever local places people sell their "junk" / "old" gear at... and try to pick up a complete system that is 30 years old..... that will be the most economical way to get started.....
bye for now
