A very simple, cheap and easy to construct preamplifier, with excellent sound quality and practically noise free.
Based on modified by me circuits from ESP Elliot (P88 Line stage) and Muffsy - Audiokarma (Phono stage PP4 and PS) with selected components and variable gain separately for Line and Phono stage.
Phono stage has capability to change input capacitance so matching with various cartridges.
This preamp made as pair for the TDA7294 power amp ( • TDA7294 DIY Stereo Dua... ) but works fine with Tube Power amplifier witch is the main amp in my system

As seen in video not exists as kit. I made this psb to combine muffsy phono stage and elliot p88 Line stage. These 2 (muffsy riaa & eliot P88 Line) exists separately as kits but the cost + shipping is high. For this reason i made my own pcb combining the 2 circuits and i bought all parts from my local market, so total cost was about 75 euro.
