Hi I have been donated / given a ONKYO A-7090 Servo operation stereo Amp.

Do I have to use a phono pre-amp for my Pro-Ject Essential turn table for this setup ?
 
Hi, you were donated a nice piece of serious HiFi Amp!. It has power to spare, is built from hi quality components. I agree with Gray above, in case of this amp and connection of Project Essential turntable, you can rely on phono preamp inside this Onkyo amp. I recommend to try some good MM cartridge like Ortofon, Audio Technika or similar. You have base for a good sounding system. BR.
 
No, you don't have to.
From the photo I saw it looks like you've got 3 phono inputs with one being for MC (moving coil type) cartridges.

Don't use the MC one for your turntable, assuming you're sticking with the supplied cartridge.
Nice one Gray, needed to know really becuase my knowledge is not that great at the moment, and the gear looks so good. Thanks

Yeah, it does look good. I did have it powered up and I didn't get a good sound, there were some dodgy connections I think and crackles whilst turning the volume dial. I have had it all cleaned out internally and the contacts cleaned so I am hoping that will solve the issue. If not, then I may have to have it stripped and serviced. Cheers

Contact cleaning on switches and rotaries is the biggest part of a 'service' Jon (and something you can quite easily do for yourself in future).
Your volume control crackles should have been cured - with no need for any strip down.
