Nobody sells guitar amplifier assembly kits in Sweden. This report will take you all the way from a request, to a complete prototype of a guitar amplifier. A guitar amplifier that will be sold as an assembly kit. A company in the south of Sweden that sells guitar effect assembly kits requested a bachelors dissertation where a student would design a guitar amp. The amp should be as simple as possible, but be able to deliver 5 Watts. This was a very tempting offer for me, a student at the sound engineering program, who loves everything related to guitars. In the report we will talk about the fundamental parts in a guitar amp. Keep in mind that this is a technical report. The report will not contain long subjective statements about what sound good or bad in my ears. I will begin with putting together a technical specification while considering the needs of the requesting company. Thereafter I will reason my way to a simple circuit containing 3 stages of amplification, based on vacuum tubes. I will design a chassis that will allow me to successfully build a functioning prototype that will meet the specifications I got from the company.
