YannLu PRE2 and PRE500 mic/DI/line preamp (Harrison MR clone)

[YannLu]

Hello,

Here is my preamp project. The circuitry is inspired by the preamp section of a Harrison MR serie console.
I added a hi-pass filter (sweepable from 40 to 730 Hz), an instrument input on Sowter transfo and a level indicator LED.

I realized a 2-channel 2U rack (PRE2):

and a 500 serie module: PRE500.

Please comment 
Thanks !

Yann
