Solar collectors with vacuum tubes
Petruška, Bohumil ; Katolický, Jaroslav (referee) ; Jaroš, Michal (advisor)
This thesis deals with solar collectors with vacuum tubes. The first part is focused on describing the function of the collectors, comparing with other types of solar collectors followed by specifications of their usage. Another topic is the heat transfer fluid that is used for transmission of heat, and therefore it is an important component of a collector. The last part deals with an application concept of use of a vacuum tube solar collector, including basic energetic and economic calculation.

Design of correction preamplifier for conventional record-player
Košarišťan, Miroslav ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
The aim of the work is to suggest the correction preamplifier for conventional record – player, show preferences for these types of wirings. Schematic action vacuum tube, its division and marking are in the first part of the work, further work attends to theory pick – up head and recording characteristics, correction preamplifier, its corrections and design wiring with vacuum tubes. Next part of the work includes comparing wiring on base vacuum tubes and semiconductor base, where main emphasis on quality vacuum tubes sound is placed. Realization of correction preamplifier and creation of the printed circuit board in Eagle program is important part of the work. Part of realization is source anode voltage and filament power supply. Measured values, show modern record – players and power supply are mentioned in the end of the work.
