Alicia is a two-box Integrated stereo Amplifier. Based on the very popular LM3875 chip. The PSU is connected via an 'umbilical cord' to the AMP. Vital statistics are: for the psu-box I used a moderate power toroidal transformer 160VA 2x25vAC and dual rectifiers with 22,400uf total capacitance connected CRC on each rail. The raw DC is connected to the amp-box which houses the voltage regulator assembly. The regulator is set at around +-28vDC. I uses Peter Daniel's pcb with the Zobel network and ci connected. The 75mVDC offset is reduced to 30uVDC using 8.3uf NP ci cap. 23-stepped attenuator and 3.9uf AEON input coupling cap is also used.







I go for this design for its simplicity and relatively low build cost with the promise of audiophile quality sound. I made this project using only basic hand tools and just brute force ( using hand saw and file )I think anyone can build this. Alice is married to Mr. Fostex FE126En in a backloaded horn enclosure. The two are a perfect match IMHO. The very good electronics qualities of the LM chip powered by a clean supply with high caps for those lovely bass + sensitive full range speaker optimized for extended lows. I build the AMP with driving a full range in mind. The sound? well... I don't know how to describe it really using big words. It just clean and sweet. Guitars and voices seem to be magnified, extended lows and highs, more than adequate for my needs. Definitely much, much better than my commercial amps. I'm very very happy!!







Thanks very much to the worldwide community of united audio fanatics @ Diyaudio!! Finally I can now listen to real MUSIC!!
