Or should I call it the telephone coin saving amp? :) It's a tiny 1 watt amp based on the TDA7052A chip. It also works well as a headphone amp. Unfortunatly it doesn't play well with dirt-pedals, but as a stand alone unit I like it. It's much cleaner then the Noisy Cricket. Vero layout here.
There was alot to fit inside the small space. Insted of a power on/off switch I went with a stereo input-jack for switching and a battery insted of a DC jack. In the video i'm testing it though an old radio with a 10" guitarspeaker from tubetown (I have plans for that radio, more on that soon...)
