I have a mixer here which is din based but a sound box for the computer
which is line based and at full up there is not enough level. What I was
looking for is a little amplifier which I could put in between one and the
other to leave and forget that has no hum hiss or other nasty habits.
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.

To e-mail, change noise into sound.

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.

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....

"Fun to solder…" Not an expression I would use :-)

OK look into that. I wonder what current it uses, Might well run on a pp3
battery then.

Bah humbug.
It just seems to be like building a floating hotel and using it as a garden
shed.

Those days are long gone. Op-amps are basic building blocks these
days. They are much better characterized than individual transistors,
and generally come out as a cheaper and easier option.
