Abstract
U ovom radu trebalo je analizirati tranzistorska gitarska pojačala u povijesnom kontekstu odnosno njihov razvoj iz cijevnih pojačala, zatim navesti glavne značajke cijevnih i tranzistorskih pojačala te usporediti njihove prednosti i nedostatke. Također, detaljno su objašnjeni načini rada pojačala klase A, B i AB. Glavni cilj rada bio je izraditi predpojačalo klase A i izlazno pojačalo klase AB. Svako pojačalo implementirano je na zasebnu pločicu dimenzija 20 cm x 15 cm. Uzete su Rickenbackerove sheme, ali nisu korišteni svi originalni dijelovi i lemljeno je ručno pa se dobiva blaga distorzija. Za napajanje se koristio naponski izvor, a signali su se prikazivali na osciloskopu. Testiranje je obavljeno pomoću bass gitare, funkcijskog generatora i mono zvučnika. Na temelju mjerenja dobivena je frekvencijska karakteristika i testirani su tonovi 𝐴3 i 𝐺4. Signali su invertirani, ali to ne utječe na zvuk.
Abstract (english)
In this final paper, the solid-state guitar amplifiers are analyzed in the historical context regarding their development from the vacuum tube amplifiers, then the main features of the vacuum tube and solid-state amplifiers are indicated and their differences are compared. Moreover, the A, B and AB classes of amplifiers are explained thoroughly. The main objective is to create the class A preamplifier and the class AB power amplifier. Each amplifier is implemented on a separate 20 cm x 10 cm board. Rickenbacker’ schemes were used, but not all the original components are utilised and it is soldered manually. Therefore, a slight distortion occurs. The power voltage source is used and the signals are displayed on the oscilloscope. Testing is performed using the bass guitar, the function generator and the mono speaker. Based on the measurements, the frequency characteristic is obtained and the tones 𝐴3 and 𝐺4 are tested. The signals are inverted, but that does not affect the sound.
