I have been using these pres since 2007 and I love them! Lets put them in a new home.I have tried to post all that I know about the units below. A12 is a API 312 clone. N72is a Neve 1072 clone.
T15 is designed are around The amazing THAT Corporation 1512 and 1646 IC. C84 is Millennia Like design! J99 is like the John Hardy 990. D11 2 DIs: I dont recall if I put the.
API 1: As you can see I have a larger collection of API pres. API 2 One of my engineers reported a "buzz" issue recently but has worked well for years.
As you know, the buzz could have been anything from the mic to the converter but I just woant to tell you all that I know. I sent this back to Tim Ryan at Seventh Circle Audio. He Rewired the input transformer.
Trimmed and re-terminated the output transformer he also, Adjusted the bias and verified distortion and frequency response to spec. Neve 2: Sound good too but the staff has frequently reported that is not a reliable channel. For what it is worth, Tim repaired my other unit for 50bucks in 2007. I would send this to him and get it sorted out.
Built by Built by Tim Ryan at Seventh Circle Audio. I'll miss this the most! T15: Great headroom and transparent sound!
J99: This was sent back to Built by Tim Ryan at Seventh Circle Audio in 2007 and repaired by him in 2011. Works well and sounds great!
No transformer install if I recall correctly. Unless noted, these were build by me or my staff. The C84, J99, and N72 were built by Tim at Seventh Circle Audio.
