Thanks Scott. I have tried a couple of type 43 cores, which only fit
about 5-7 turns, and they make no difference at all. Apparently type
43 is for supression of 30MHz+ though. I have about 12 ft of speaker
cable running to the rear speakers.
I get RF into the amplifier on practically every connection -- audio
and video from the VCR, audio from the turntable, etc.. quite frustrating.
I can't see type 77 cores in the catalogues of our biggest electronics
retailers so I'll have to dig a bit deaper.
Thanks,
Hamish

Does anyone have a TNC2-H for sale. It's the 9k6 tnc also known as
TNC2h-DK9SJ.
A TNC3 dual version would also do.
Prefer UK please.
Thanks
