Since I have serviced several Neve 1073 modules and Neve consoles I was excited to open up the GA73 and have a look inside. What I saw impressed me and I am sure it would also impress Rupert Neve himself with how closely the circuit follows the original 1073 drawings that I have from 1973. It also sounded really good out of the box and you would have to get up toward nearly $1200 a channel to get something that compares in sound and features I think.
The only difference I noticed right off was that the GA73 used electrolytic coupling capacitors where Neve used tantalums but this would only increase the price about $15. The tantalums are a little more accurate and generally considered more “HiFi” than electrolytic capacitors. The heart of the Neve 1073 and a good part of the sound is derived from the 23 position gain switch which varies in 5db steps from -20db to -80db. Cheers, Dave Thomas Advanced Audio Microphones. Goldpoint Level Controls. Uneeda Audio - Build your own attenuator pads. A question that pops up frequently is that of building atteunator pads.
Here is what you need to know, in one place. What is a Pad? Where can I use them? A pad is nothing more than a network made of resistors that creates loss (attenuation) in a transmission line. Pads can be designed with many different attributes: matched impedances, unmatched impedances, etc. A thorough treatment of the subject can be found in the following (among others) references: The Audio Cyclopedia, 2nd ed., Howard W.

Original Article by Kent Williams: For home studio guys, getting rack boxes are a real problem.
They don't make any sound, yet they can set you back hundreds of dollars. If you have a few basic tools, though, you can build cheap racks. Here's how: A rack is a box. Boxes are easy to build. Materials & Tools needed: 3/8" Interior Plywood (1/2 4'x8' sheet for one rack) 8' 1"x1" pine board strips 1" sheetrock or wood screws. EITHER: Pre-drilled rack rails & matching mounting screws OR standard shelving rails & 1/4" furring strips. 1/4" machine screws (with big heads) 1/4" screw tap & matching drill bits Saw, drill, tape measure, screwdriver and/or screw bits for the drill. The first decision is how deep to make the box. For width, the rack units themselves are 19 inches wide, but you want to add a 1/4" or so for some slack on the sides. Height? It's Hip to Be Square Now you have to cut some plywood. 3/8" plywood is thick enough.
To construct a stable box, use screws. Good Screwing Made Easy. JLM Audio Shop.
