A relative is slightly deaf and gets annoyed when he tries to listen
to the TV because his hearing-aid picks up all sounds in the room.
His TV does have a headphone socket, which is great when only he wants
to listen to the TV but is useless when anyone else wants to listen
too: he sets a `reasonable' volume for the headphones which makes the
loudspeaker volume too high.
I bought a small general-purpose amplifier from Tandy (Radio Shack)
and connected it up to the headphone socket so that he could adjust
the volume to his own requirements without adjusting the TV volume.
The trouble is that at a reasonable TV volume the little 9v amplifier
clips when its volume is turned up too much: giving an annoying buzz
in the headphones. The tone is not too hot on the little (cheapo)
amplifier.
There seem plenty of articles regarding TV amplifiers in popular
magazines, but they usually use a microphone close to the TV speaker.
The directness of the current set-up is very desireable,
but I'd like to cure the clipping and the lousy noise output from
the current configuration.

Any ideas out there would be welcomed. I thought that one possible
solution is to attenuate the `headphone' signal which comes from the
TV: I think it is too strong for the little amplifier.

Thanks
Mungo Henning
P.S. I may not get back to any replies for a while, but I'll do it
eventually.
