After the very interesting, but quite confusing, thread about "preamp
issues" called "EIN values and bits and peaks" discussed here, I made
an effort to solve the agony with choosing recorders cause of their
(actual or presumed) preamp noise!

It is a light weight plastic box with a 9v battery. It has two slide
switches, one that is switching the battery on/off and the other one
switching the gain between 55db and 35db. There is a 3,5 mm input
for a PlugInPower stereo microphone and a 1 meter output cable with a
3,5 mm male.
* No more worries about recorder input noise values!
* Current regulator gives the lowest noise possible for all PIP microphones=
.
* You can use long cables from the microphone to the Telinga preamp.
* Clipping output level is 700mV RMS into 2,2k
* Total weight is only 160g incl. battery.
* Current consumption is only 2mA (Sic!) which means that it
runs >100 - 150 hours on a 9-volt alkaline battery, depending on the
needed plug in power current.
Even though the use of transistors and other electronic's is
uncontroversial, this kind of preamp design has never been made
before! As I see it, it must be ideal for naturesound recordists.
If it will become an official Telinga Preamp or not, depends on the
interest. I will make 5-10 in a first batch, to be delivered in 6
weeks. It will be sold to members on this list for 200 USD + shipping.
