One of my turntables is creating a sound I can only describe as a scratchy kind of white noise any time a record reaches any relative high ends. Ultimately frustrating as you can't fiddle with the EQ's otherwise it gets worse. Recording mixes is almost pointless... Initially I thought it was my carts, swapped them over...still the same. Checked wiring, cleaned dusted etc. Plugged all back in, same problem. I'm pretty much decided it has something to do with the wiring inside the deck. Either the earth or the wiring for the tonearm (which was recently replaced) is at fault for this scratchy white noise. It is 100% worse with older tunes...recording it just is painful to listen to. Anyone had this before? My 1210's are as old as fack so I'm willing to send em to Mistanoize, but just wanted to see if anyone else has had any previous issues that are similar... thoughts?
