As demand for solar panel installation has risen sharply, especially for installations larger than balcony power plants, the order books of solar companies are full. If you ask for a quote today, you may have to wait a while, if your request isn't simply postponed indefinitely. Another consequence of the solar boom is that some companies are charging very high prices for installations. Yet there is an obvious and radical solution to the problem of excessive prices: Do it yourself, as the English say. The price of materials is currently affordable, and it's the ideal time for those who do the work themselves. They couldn't save more. Add to this the satisfaction of doing something useful, both economically and ecologically, and the pleasure of building yourself. In this special issue, you'll find a wide selection of Elektor assemblies, from solar panel controllers to solar water heaters and solar panel orientation systems.

Met ringkern-uitgangstranformatoren Buizenversterkers vormen voor velen het neusje van de zalm, wanneer het gaat om de versterking van audiosignalen. De combinatie van klassieke techniek met moderne componenten heeft geleid tot een ware revival van de buizenversterker. De toepassing van de in de afgelopen 15 jaar door de auteur ontwikkelde 'ringkern-uitgangstransformatoren' heeft daar mede toe bijgedragen. Opvallend aan deze transformatoren zijn vooral het extreem grote frequentie bereik en de geringe lineaire en niet-lineaire vervormingen. Het hoe en waarom van de transformator wordt op verschillende niveaus uitgelegd, beginnend bij inleidende begripsvorming en eindigende bij complete wiskundige beschrijvingen, waarbij ook de samenwerking van de transformator met de buizen en de luidspreker centraal staat. Naast de beschrijving van schematuur en zelfbouw van eenvoudig na te bouwen moderne high-end buizenversterkers met een uitgangsvermogen van 10 tot 100 Watt, worden bijzondere buizenversterkers met ringkerntransformatoren besproken: innovatieve oplossingen voor perfecte audiokwaliteit. Zowel de zelfbouwer als degene die kennis en inzicht wil verwerven in de complexe materie van transformatoren, buizenversterkers en audiosignaalverwerking zal dit boek met plezier ter hand nemen.
