RFI unbound: when I was a kid so many decades ago, I had a friend that lived across the road from a fifty thousand watt broadcast am transmitter. When I went to his bathroom, his house radiators worked like a tuner. And the copper played the radio out of the sink. No kidding. Leaping from '69 to '99, I was listening to my cd when orders came from the boss to go to the store for milk. So I get in the car im my garage and the radio comes on. At first I think, how weird, I was just listening to 'El Cant de la Sibilla' in the house as I realized how stupid I was for thinking even for a second that would be on my radio. On the other hand maybe it is bleed through. Do the above mentioned test.
Turntable as tuner?
My turntable seems to be picking up a radio station. Also {maybe this is related?), I have to turn the volume way up (compared to the cd player) in order to listen to records at a reasonable level. The turntable is a Pro-ject RM4 w/Project 9 tonearm & Sumiko Pearl MM cartridge connected to a Pro-ject Phono Box and B&K PT3 preamp. All the connections (including the ground) seem tight. Any ideas?

Finally fixed the problem with a pair of AudioQuest RF Blockers (RS wanted $21/4, the AQs wee only $4 more and seemed to be much higher quality) on each cable and a pair of All Clears on the TT phono stage cable. Nothing less seemed to work. Thanks to everyone for the help! P.S. The rest of my system sounds better now, too, esp. bass. Synergy... |
Well, I _thought_ that the ferrite things had fixed the problem, but I was mistaken. It turns out that (although the interconnects were a part of the problem), the real culprit was the cable on the wall-wart that powers my Project Phono Box. Wrapped it around a couple of the AQ RF Blockers and Presto! no more noise. BTW, during all this I decided to try shielded coax interconnects from Blue Jeans Cable (http://www.bluejeanscable.com) & love them! Cheap & tasty is best... |
