Humph, well i thought it was me.
a single transistor stage with, say an emitter follower would suffice
though these days the over designers would probably use an Ic.

Anyone seen anything like this around?

You'd think they'd be common, given how often this sort of thing arises.
But they don't seem to be.

Under-designers, you mean. With an IC you don't have to do any design
- just set two resistors to give you the gain you want.

And that is exactly how I would do this - it's by far the best way.

If you don't want the faff of getting the bits and building it then
N47FL at £6.99 from Maplin will do the job. Uses a NE5532 amp chip so
should be very low noise. Supply is 3-25V so any old PSU you have
lying around....

Was it Brian that was looking for it? I thought it was Duncan or Dave.

Brian might have a problem with it as it is in kit form!

I'm sure he can find someone happy to put that together.

They do one with flying leads on it, still require soldering mind...

I would be grateful if contributors would make sure they attribute
comments to their sources. The quote above is exactly what I wrote
and I said nothing about 'fun to solder.'

Mind you if you have been taught and know how to solder properly it is
easy and can be 'fun.'

Sigh, I'll have to talk nice to some sighted people with soldering irons
then won't I? Not quite figured out how they make up 22 bits for such a
devce.
Still.
