The Blue Velvet Tube Pre-Amplifier

My second tube audio DIY project, The Blue Velvet tube Preamp by Dick Olsher.
The only changes from the original schematic is the use of a 6X5GT tube rectifier. This is an excellent preamp. The 6SN7 tubes by KENRAD gives deep lows and velvet mids - highs. Coupling caps are Mundorf Silver Oil 0.68μF.
