Pioneer PL-100 With PC135 Cartridge & Stylus

Post by toys4steve » 25 Dec 2019 14:54

I have a Pioneer PL-100 turntable. It probably has the original PC135 cartridge & stylus on the tone-arm. I am getting a low volume amplification from the stylus/cartridge and I do not know why? Is something wrong with the cartridge? Could it be wired wrong? I checked the wires and they are color matched correctly so I do not know what is causing the low amplification of the sound. Can anyone help? Thanks, Steve

Hi, you forget to mention what the turntable is hooked to. If you are using a newer surround sound system then it most likely does not have a built in phono pre amp. A phono pre amp is needed to boost and equalize the sound from the cartridge so you can hear it from the speakers. If the equipment you are using does not have a built in phono pre amp then you can buy and external phono pre amp and hook the turntable to it. Then the phono pre amp can be hooked up to the equipment you are using through any line level input. Something like Aux, DVD, CD, ect. Now if you are using a receiver with a built in phono pre amp then it could be a bad or dirty stylus causing the poor sound. It could also be the phono input is bad and in need of servicing. Before we can give you the correct answer let us know what other equipment you are using to play the turntable through.

If it turns out that a preamp is needed in your situation.

I have it hooked up to a Yamaha RX-V595a surround sound AV receiver. I attached the cords to the front aux inputs on the unit and not the rear inputs. Should I try the rear DVD or CD inputs or will that not work either?

That will not work..........

The turntable outputs NEED to be plugged into the 'PHONO' input of your Yamaha.
A single pair are found amongst the rear lower left hand RCA connectors. (right next to the CD input)
Note: This is within the 'Audio Section' on the back of the amplifier.

Using the large INPUT Knob on the front, you then need to select PHONO.

You may wish to consider a new stylus for your cartridge, particularly if the original has been well used.

I have my Technics Turntable plugged into the CD jacks in the rear of my Yamaha and the turntable plays just fine. I removed the Technics RCA plugs and substituted the PL-100 RCA plugs into the CD jacks and it still outputs a very low volume. So it is not a pre-amp problem. It must be the cartridge /stylus. Before I spend money on a new stylus is there any other thing I can try? I cleaned the stylus and it was dust free.

Look at the English Instruction/Owners manual for the Pioneer PL-100 page 5
https://www.vinylengine.com/library/pio ... -100.shtml

Connecting the Pioneer PL-100 to the CD input on the amp is NOT correct.

The output from the turntable should be plugged into the 'phono' connection.
You NEED the preamp in your amplifier (via the phono input) to obtain a reasonable volume with the Pioneer.

The Technics turntable is another issue:
Which Technics turntable are you comparing to the Pioneer ?
-it could well have an inbuilt preamp?

There is another very important reason why it is NOT a good idea to plug the Pioneer turntable outputs directly into the CD or line inputs of your amplifier.
Because RIAA equalization will then NOT be applied to the signal as it should.
Preamps usually do 2 things:
1. They amplify the low level signal from the cartridge.
AND
2. They apply equalization.

Toys - check to see if your Technics has a phono preamp built into it. If it is relatively modern, it may. Which is the only way it would sound okay though a line level input. Turntables without phono preamps have to be plugged into a phono stage, both for proper volume and for proper equallization.

The OP's amplifier: Yamaha RX-V595a has a phono input which should be fine with the Pioneer PL-100 TT

And if the Technics has an inbuilt pre-amp as seems likely, then that TT can occupy one of the line inputs.
