Hi

Do you know a diyaudio project for a complete opamp based preamp

with simple source selector, simple volume, RIAA and maybe bal / unbal / bal ?

without microprocessor or lcd

thanks

ESP has lots of audio designs to choose from.
Mr Huff has an excellent design based on D. Self designs. Analog line level contains more info.
