trying to get the most out of my pre-amp

Post by unification02 » 06 May 2006 03:23

I've had a turntable for a couple years now but just recently got serious about it. I used to have this battery powered Radio Shack pre-amp, but I just got a McLelland RIAA-80 pre-amp and when I turn it up real loud I still get hum/buzz like a bass buzz. My ground wire is connected to one of the screws on the bottom of :?: my turntable (it's a Sony direct drive ps-t1....i got it off of a friend and it looks like the ground lead was maybe ripped out) and of course the pre-amp has a ground lead. I'm running it through a Sony str-de185 reciever and Sony ss-mf650h floor speakers. Is there any way I can inprove my sound without spending a whole lot?

Hi 02

Could there be a mysterious earth loop? What happens if you remove the added on earth wire from under the tt? Still 'buzzing'? If you have a multimeter, set it to 'continuity', touch the arm and the place where you added the earth wire. If these two places do not have continuity, I suggest you try to run your earth wire from the arm bearing tube inside the plinth.

Post to let us know what happens.

Cheers

You can also try to move away the pre-amp from your receiver. if i got this correctly,you are using your pre-amp as a pre-amp and the receiver as a power amp.The phono stage of your pre-amp(all phono stages for that matter) don't feel happy when they are sitting close to power supplies.

It's all good I fixed it. All I had to do was move the pre-amp a little out of the way of the receiver and tighten the ground connects real tight and it is as smooth as butter. Thanks for your suggestion though.
