En gitarrförstärkare baserad på elektronrör har konstruerats på uppdrag av Mikael Lyander, ägare av Sandkvie Studio på Gotland. Arbetet med gitarrförstärkaren Dual 30 har gett stor insikt om designprocessen av en rörförstärkare. Moment som design, layout och praktisk konstruktion har behandlats. Både författarna och uppdragsgivaren är överens om att förstärkaren lever upp till de uppsatta målen..

As the way of communicating and accessing information has changed radically over thepast decade so has the way the public libraries operate to reach the citizens. In thesetimes the demands of what a public library should be and offer the visitors havechanged. One should have the option to access the digital public library at any givenhour of the day, from anywhere in the world and at least have the same possibilities ofinformation as the visitors at the non-digital, "real" library.In this Master's thesis we will analyze and discuss the condition of the Swedish digitalpublic library of today, 2006, and the forward thinking work with the issues ofdevelopment in this matter. In order to do this we set out to examine the attitudetowards the public digital library among the staff at a small number of Swedish publiclibraries and their supporting institution, the county library. Moreover, the attitudesdefined have been compared to the actual status of the services and medias at the publiclibrary websites.In conclusion, we have detected a certain standardization of what the digital publiclibrary consists of today.
