Re: turntable setup into an hp 7590
In theory as long as you have a sound card installed, yes you can connect your turntable direct to your computer simply by connecting it to the audio input.
You will probably need a patch lead with twin line phono connectors on one end and a stereo 3.5mm jack plug on the other end.
Please note, the turntable or phono inputs on amplifiers are unlike all the other inputs, because they have a particular frequency response tailored for use with a headshell cartridge.
If you connect your turntable to an input that has not been tailored to the RIAA response curve, it will sound tinny. This is what probably happens when you connect to your computer. The input may also not be sensitive enough.
You may be able to adjust the frequency response if your sound card includes an equaliser. Alternatively, you may be able to download some audio software that will allow you to equalise your turntable.
All in all though, I'm sorry to say you would be better off with an outboard preamp.

You need to get a special connector. Image of the type below. The red and white connectors connect to the RED (right) & WHITE (left) connectors of the turntable. The yellow is for video. Search Amazon for it.
Connect the RCA phono plug wires usually red and white wires with plugs to a receiver or amplifier in the back of it to phono in. New receivers will not work unless you have a phono preamp. Best to buy a vintage stereo receiver or amplifier with the correct connections. Make sure you connect the ground wire which is usually a small black wire coming from the turntable to an receiver or amplifier. Turn the stereo receiver on phono. Connect it to any screw attached to metal on back or look for a ground screw. If you do not attach it it will hum. http://www.hardwaresecrets.com/imageview.php?image=357
The red wire is the right channel, so going back to your amp, get a single phono plug with with the wire exposed, so you can touch the wire. Then remove the turntable connections. With the amp on plug the the lose wire plug into each channel and check if the sound on the right is still low. If it is then there's a problem with the magnetic cartridge pre-amp inside the amp. They are often located near the phono socket on a seperate PC board, but if not just follow the red wire to the main board. Chances are it will be an IC that's failed.
If it has a strong buzz at the back of the amp. Then I should replace the wire between the turntable and the amp. Or the right phono plug that connects to the amp.
plug a red and white rca cable into the back of the turntable and then plug the other end into your phono output at the back of the amplifier.then turn your selector on your amplifier to phono.wowla you should have sound
there is a switch that cuts off the signal when the tone arm docks.check the wiring is not broken inside and that the switch is ok.typically,red green white black red and white are plus and left ground is green and right ground is black.the collar that screws on to the head unit has 4 pins.make sure the contacts are clean.measure the wires one at a time from the tone arm to the rca plugs on the back.the green and black go to the outside collars,and the red and white go to the center pin of the rca plugs
