[UK-CONTEST] TV DISTRIBUTION AMPS

[Don Beattie]

Firstly, sorry to cross-post to both reflectors, but I am looking for a quick reply !

My one and only neighbour has a problem, which I need to help him get fixed. He has had, for some time, a TV distribution amplifier in his loft, and I had to fit torroids to it to make it immune to HF. Now, however the amplifier has gone unstable. We did some tests today, and it is awful - to much gain = oscillation. To little = lousy picture. He wants to replace it.

The question is, does anyone know whether there is a "good" distribution amplifier which has reasonable high immunity to HF ? If so, I'd really appreciate details, as it would be nice to start with a reasonable level of immunity.
