Sorry it been so quite around here I have been keeping my self rather busy of late. But here is an update on one of the projects that I have been working on.

I am in the process of building four NV73 microphone preamps for someone local. This is a really cool kit, I would not recommend it as a your first microphone preamp kit to build as it is rather complex and can take a bit of trouble shooting.  Here are some photos of the build. I currently have two finished and two more to complete.

Neve 1073 PCB Layout

Day 1

If you have been following along over the last year Sammy and I have been building a Neve  1084 clone.  Check that out over here.  We started with smaller 5cm X 5cm pcbs that had the individual stages on them, now we want to go towards a larger PCB that includes the gain switch as well as the three amplifier stages.

I went for a 10X10cm PCB I am hoping that I will be able to get all the parts into that tight of a squeeze with out it being extremely hard to populate.  I may go back and change the resistor foot prints currently they are will allow both SMT as well as through hole parts. If space becomes a major issue I am going to change to through hole on end like I have done with the other PCBs.

So here is the Neve PCB Layout as right now.
