Ah, I remember that one Marcel, Jaycar Electronics used to stock the parts kits for the Valve preamp along with the power supply kits, unfortunately Jaycar discontinued the kits a few years ago.
As a point of interest, Valve technology has one big advantage over Solid-State technology, if in the unlikely even an EMP (Electromagnetic Pulse) was triggered, one of the two different technologies would instantly cease to work and the other would carry on working, as it turns out, Valve technology is relatively immune from the damaging effects of an EMP.
