hello and welcome, I believe I have sent you over here from instagram right?
It's right to do an introduction but as others have mentioned you will probably get more of a technical response on solid-state or another sub-forum. When you post there, try to provide as much background detail as possible, like was the setup ever working together for you, or they are unknown pieces? Also there are a couple of things you can test and provide info on in your thread. for example, you can hook up your TT into Aux and see if anything comes out (it would be quiet even if it works, since TT signal very low level); that will test the output from the TT. And, you can test you phono input by hooking up another device such as a phono (with 3.5mm to RCA cables) with phone set on very low volume (remember phono signals are at least 10x smaller than what you get from line level). That way you can at least know which device is playing up.
Drop a link to your new thread here when you start it up.
Cheers
