|I have made some nice and interesting investigations together with Mr. Lukasz Fikus from Poland (better known as “Mr. Lampizator”) along Single Ended Triode (SET) tube amps, which led to the redesign of the Chinese Music Angel 845. I received so many eMails for this project that I decided to build my own homepage, where I could add later revisions from the original article and a FAQ page (unfortunately still not ready!).

Also in the
order of Mr. Lampizator I later designed the FETishizator,
an output stage for DAC in CD-players, as a complement and/or
substitution for his well known Lampizator tube
stages. The benefit of the JFET solution is that there is no need for
an extra power supply for heaters and anode voltage, while not changing
the tube-alike triode sound.
solved the problem of best coupling the S/PDIF signal to digital
You will find
here some HiEnd-Audio projects from the field of tube
design as well as some projects in JFET technology.
The JFETs have nearly the same behavior as the tubes, especially when
using them instead for triode circuitry.
I made up a
special theory, when using JFETs as a substitute for tubes, called “STC”, which is in
full spelling “Standard
I call it this way, because the original tube schematic can be taken
and “translated” into a JFET circuitry, while all
parameters stay nearly the same.

I shall try to
answer all your questions (mailto: ) concerning
the several projects, but I can not promise due to limited resources
