[UK-CONTEST] TV DISTRIBUTION AMPS

[John Wilson]

Don,

You need  www.proception.co.uk   These amps were designed by an amateur 
friend of mine.  Two of the main design criteria were for them were a) 
to be unconditionally stable and  b) for the ones with built in 
filtering,  to have filters that cut off between 470 MHz and 440 MHz so 
that they don't get overloaded by 70 cms transmissions.

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.
