The design and construction of combos for electric guitar. Work discusses how theories of construction and design blocks combos, so its structure and measuring its parameters and parameters of individual blocks. Bachelor thesis has the aim to get acquainted with the problems of the design of individual parts of the combos, which are the preamp with a proofreader and an end-amplifier implemented as an integrated amplifier circuit TDA7293V. This solution was chosen due to its price availability, simplicity and parameters, which amplifier despite this simplicity reaches.
Guitar Amplifier TDA7293
The combo also will be equipped with two built-in guitar effects, and the effect of the fuzz and tremolo. Their choice was influenced by future use of combos. The work also contains proposals power supplies for all parts of the combos, as well as a description of the used speakers. The desired characteristics of the involvement of effects (fuzz, tremolo)and preamps are also simulated in the program PSpice, the other parts are given at least the value declared by the manufacturer, and subsequently also measured on real circuits. Also are the characteristics of the baffle combos.
preamplifier Involvement correction preamplifier , PCB in Annex A.3, it does include the supply voltage of ± 15 V for the preamplifier comes . It consists of two low noise operational amplifiers TL071 has minimal distortion. Capacitors C2 and C3 are used for the upper limit width bandwidth of 160 kHz, and prevent high-frequency oscillation.

TDA7293 Bridge Amplifier Circuit LM1036 Tone Control
The choice of the hi-end-amplifier TDA7293 Power amplifier TDA7293 from the company ST Microelectronics are the most widespread power amplifiers available in our market. Even if his own conception is integrated, contains a number of protections, which greatly contribute to extending the life of the entire amplifier.
TDA7293 Gitarren Combo Verstärker Projekte
Das design und die Konstruktion des combos für E-Gitarre. Die Arbeit beschreibt, wie die Theorien der Konstruktion und das design der Blöcke, Kombos, also seine Struktur und die Messung der Parameter und die Parameter der einzelnen Blöcke. Bachelor-thesis hat das Ziel, die Bekanntschaft mit den Problemen der Gestaltung der einzelnen Teile der combos, die den preamp mit dem lektor und ein end-Verstärker implementiert, die eine integrierte Verstärker-Schaltung TDA7293V. Diese Lösung wurde gewählt, aufgrund seiner Preis, Verfügbarkeit, Einfachheit und Parameter, die die Verstärker trotz dieser Einfachheit erreicht.
