Radio Shack preamp noise

Mike Riley · 18th June 2007, 02:05 PM

I'm beginning to try and transfer music from my old record collection to a PC. Trouble is, using a radio shack preamp (which is properly grounded) I am getting some kind of amplified noise.

Can anyone offer advice on why this is... is it simply a question of cheap hardware, or can the noise be isolated and removed?

Thanks, all. ... Mike

Since you call it a pre amp, is it even a phono amp with RIAA correction? Otherwise it is not suitable at all.

Maybe "properly" grounded is not as proper as you think. Try using an IEC power cord with a broken off ground tab on the PC. Sounds like the oh so common PC ground loop.
