Hi all!

I have a problem with my Rega Planar 3 TT fitted with a Rega RB300 arm re-wired with Cardas and fitted with an Ortofon OMB5e (MM) Cartridge.

I am running the TT with an external Pro-Ject Phono Box SE.

I have this audible 5-7Khz noise that lasts for 5-10secs eaach time and it comes and goes even when the table is running or not running, be it if the arm is lowered or not. The noise comes from both channels equally.

I managed to borrow an oscilloscope from a friend and I've managed to isolate the problem to the TT only. I've consulted a professional and he said that it could be environmental problem. As I am staying quite near to a TV Broadcasting Station.

Some ideas on how to solve this problem please?

Thank you.
Tim,
Singapore
