Here is a small but good amplifier. Its a project that a picked up somewere in the internet, I don´t know who is the author but i like very much this amplifier. Well its based on the TDA2052, It Has PSU integrated.
I´m trying to design one new 5.1 amp based on 5 TDA2052 for mid/high and 2 TDA7293 in bridge for Subwoofer, when i finish i´ll post here, I think it will be better use a SMPS to power this amplifier, normal PSU will not fit in a small case as well it will be too heavy, but i´m new on SMPS, when i finish it i´ll send to you. Would you mind if I ask your help by the time i finish the amp part, with the SMPS?
I finished a new version of this amp, its now using a smaller bridge of 8amps, and i raised the capacitors to 5600 uf per rail to increase the bass.
I'm doing some tests and by the time its done i'll post the new lyt.
