Default New Pre amp thingy

Hi All
Ok so here is the new Buffer Pre I had it up and running last night just with a single input for testing running it from the WDPSU3s 200-volt line and it sounds very good a little darker perhaps and has more depth and wider sound staging than the WAD CF Pre.

I am going to keep running it for a time just to see if I will stick with it then I may put it in the CF Pre Case with a new relay board from Mathew

The good thing is as I had most of the parts to build it to hand it has only cost me less than a tenner to date for the PCB which uses three valves two 6922/12au7 I am using two Russian 6H1-EB and a JJ12A7
Take a look at the Schematic and give you opinion on it images here
