Phono.. does this mean?

Yes and No
It probably definitely means that a moving magnet (MM) cartridge would work, it might also mean that a moving coil (MC) might not work, depending if it was a High Output(HO) or a Low Output(LO).
Check the specs, if you can find them, and see how much gain you have for the phono, if under 50 low output moving coil is probably not going to work. If under 40 High output may or may not work.
But if under 50 or 40 and over 20 or 25 a moving magnet probably will work just fine.
Hope that helps.

Not always,some companies install phonojacks for connecting a phono preamp.My Rogue TempestII has phono jacks but no phono stage.Your manual should tell you if you have a phonostage.If you don't have a manual,search the web for one.The company that made your unit will more than likely have one on their web site.Also,post your equipment and someone here will probably help you.Good luck.

I don't know what receiver you have but, an "old receiver" that says/has phono input on the back, with a selector switch on the front that includes phono, means yes, you can hook up a TT with MM cart. If your receiver is capable of MC cart, it will have a selector switch on the front which you can select between MM and MC carts. Never hurts to do what Tpreaves suggest either.

Thanks folks. I have a Yamaha RX-V2300 I have used for years. I want to make a dedicated system for my TT someday, but now is not the time. I will have to search for the owners manual.

Not sure what you mean by MM cart? Dont most "Used" TT's have everything I would need to plug and play?

Oak244 come on seriously you haven't been on the Gon to long. MM for moving magnet and MC moving coil.Some TT such as the Music halls come plug and play and many of the budget Regas{cartridge included}look at these along with any TT on the Gon that the owner is selling used and has a mounted cartridge installed. I would say if you purchase the latter and have it shipped you most likely will have to reset the cartridge because of shipping.
