Discrete Preamp

My discrete preamp, which was based on the information in this Zetex datasheet.
There is also a PCB layout for this available on the downloads page.
It would be quite trivial to construct this on veroboard (as I did with my prototypes) but the PCB layout provided makes for a neater job.
This little preamp has excellent performance and very low noise. I have compared this to several commercial designs including Cambridge C500, Rotel RC971, Adcom GFP345 and it compared very favourably.
You can see some pictures of the completed article on the gallery pages.
