33609 Metal Knob: two 33314

3609C... Incorporated all the mods/improvements that I begged Neve to incorporate when I worked there. Recadded motherboards with IDC connections, LM317 PSU, pressed steel case, neon rocker switch.

robust power supply and the amplifiers used the BA640 IC based cards, as opposed to the earlier discrete BA440 cards

The new 640 had more headroom and a faster recovery time after clipping, which was important for broadcast use. Another difference was based on the transformers, the C used Belclere transformers, as opposed to the Maranair/St.Ives of the original version.

33609J... AMS-Neve's current offering, J = Japan, the main client. I believe that it's a repackaged C though I've never peeped inside one. I'm not fond of equipment that includes the word "classic" in its title...

33609J/D

The J was non-discrete as the C had been, so shortly after release and following the requests of many users, AMS Neve turned the J into the 33609 J/D version. The "J/D" stands for "Japan Discrete" and went back to the BA440 type amplifiers of the earliest version, which many end users preferred.

33609N

The most recent iteration, the 33609 N, uses more modern construction techniques, similar to the 1073N. The transformers are now of the Maranair branded variety that AMS Neve is having custom made for them to the original specs of the earliest version. The look of the unit harkens back to the original "Metal Knob" a bit more. They have added a fast and slow switch to the compressor attack time, which none of the other versions had. The unit remains discrete and has a sound very much in line with those originals. There is also enhanced "I/O" switching on this newest version.
