Abstract

This thesis deals with design of vaccum tube audio amplifier implemented as a push-pull in the class B with end-EL34 tubes. At the first, it describes the function and the feasibility of individual blocks. Subsequently, selected the best solution and designed the overall concept. With programs MicroCap9 for design scheme, Eagle for realization of printed conductors and Autodesk Invertor for design chassis. The entire structure is designed with a view to maximize the quality and bandwidth usage. There are reported differences between the vacuum tubes amplifiers, transistors and integrated circuits in terms of their construction and use. At the end it was measured characteristics and behavior this amplifier. All documentation for the production are included in attachment.
