If you filter for my posts in this thread you’ll see my impressions from when I first got it. And our discussion of the attack issue (with images and some numbers). Like I said above, if it weren’t for the attack issue, it would be a perfect box, because the tone is lovely. I still use it for that reason, but going through the tracks in PT and manually fixing the big transient peaks it can’t catch (and exaggerates) is a pain in the ass. FWIW, I had the same issue with the Warm and KT. Strange. I’ve had 4 WA76 through here (still have 2) and I had a KT76 briefly and both of them controlled dynamics like you’d expect and could absolutely level a signal. Joshua has said he specifically avoided that FET (which I think more or less everyone uses now) because, although it levels better, it doesn’t sound as sweet. And I agree with him there, the ADG has a sweeter tone to it. But it doesn’t level like you’d expect out of an 1176. It can’t quite lock a signal in place assertively. Has that weird initial transient thing. |

Stam took care of the invoice issue. Hopefully I will get to actually test out the new design before Christmas.
I have a few mix projects slated for December so... Here's hoping!

Nice, fingers crossed you get a nice present under the tree.

I really liked the sound of the A circuit. Although it's called an A, I believe it's the AB circuit. It's fairly accurate too. It sounds like an A for the most part, with just a little difference in soft barely noticeable distortion on the ~8K and up range, which is part of it's compression. A couple of other posters are right about it not catching every quick and sharp peak, like you would expect. This is especially true in 'A' mode. Somewhat in D mode and hardly as much in G mode. At least on my two. |

Doesn't cover everything, but enough. www.mixonline.com/recording/1176-revision-history-372048 Here's a little more detail on the A: mnats.net/1176_revision_a.html And here's the actual A schematic www.proreplicas.com/gfx/urei-details/schematA.jpg And all the cloners are reading this: groupdiy.com/index.php?board=27.0 There are some great DIYers here, plus we have audioscape and stam visiting, and resident helpful experts like matt@IAA and svart amongst others who can weigh in on minor differences and make corrections. For Example: Should R12 be a 1K or 2.2K? Which is revision A and which is revision AB? |

For Example: Should R12 be a 1K or 2.2K? Which is revision A and which is revision AB? I don't really know much about it, to tell you the truth. As far as I know, the only difference between the A to the A/B is that the later has less noise. But I'm sure it may be more than this. My comment was just that I remember Joshua himself saying that the Stam was the A, and not the A/B. But I could be wrong and my mind playing tricks on me. Maybe he can chime in and clarify. |

Well I remember the “a”, circuit having this little edge, so guess it was that 8k distortion, just made it a little clearer for me: really liked it a lot!

So, what you think about it? Reliable? Any problems? And what about the sound? Have you compared with another hardware? And plugins? If you filter for my posts in this thread you’ll see my impressions from when I first got it. And our discussion of the attack issue (with images and some numbers). Like I said above, if it weren’t for the attack issue, it would be a perfect box, because the tone is lovely. I still use it for that reason, but going through the tracks in PT and manually fixing the big transient peaks it can’t catch (and exaggerates) is a pain in the ass. I literally mostly use the 1176 to exaggerate peaks. |

I literally mostly use the 1176 to exaggerate peaks. This is more like, ok you want your snare to smack in a certain way so you get it set for peaks of around -8 but the first hit (and any where there hasn’t been a snare hit for a few seconds) go all the way up to 0 and clip. It’s not that it’s systemically slower it’s that it doesn’t catch initial peaks in a predictable way. And when you’re punching up a vocal or whatever and don’t want big peaks, you can’t really lock it in place like you can with any other 1176. Random consonants will have enormous spikes to them that you have to clean up in the DAW. |

Just eyeballing the common source JFET stage and the value of the drain resistor and first source resistor/bypass capacitor, I think has to be closer to 2.2K for better operation. it would probably work at 1K but would draw more current and probably clip on the negative peaks of large amplitude signals. Do you mean true Rev A vs. Rev B or something in between, or do you mean the difference between the Class A outputs and the Class A/B outputs of later revisions? |

The Rev A would be 1K, The rev AB should be 2.2K AFAIK. And I think they stuck with that for Rev B. I understand the appeal of the 8K and up 'smear' But I really REALLY REEEAAALLLLYYY love my audioscape bluestripe 76a for the fact that when I need it, the attack is even faster than an original (like 10 microseconds) and cleaner so I can karate chop the peaks off - but only when necessary. And I really am just a life-long student in the field of electronic design and causation, yielding to the much greater knowledge of you all who work in electronic design and implementation on a regular basis. |

That resistor would have nothing to do with attack times. The rev A has different attack resistor/capacitors, larger resistor and smaller capacitor for faster attack. |

I should have been clearer about it's just one difference I noticed... and then we got onto the attack discussion, and waters get muddied. |

I still use it for that reason, but going through the tracks in PT and manually fixing the big transient peaks it can’t catch (and exaggerates) is a pain in the ass. Just change the Jfet brother. I'll work you through it. You can use the same one everybody else is using but you will need to upgrade the transformers to Sowters to make up for the "tone". Output transformer model is 1327, www.sowter.co.ukI can work you through the entire thing and send you a tutorial or we can have Jeff do it in the US. All ADG's from the second batch onwards use the standard JFET and new upgraded optional transformers I have tested every single transformer in the market for the 1176, dozens of them. I thought of making a switchable model that has both Jfets inside but I have hundreds of orders to catch up on first and the ADG is already too complex as it is. It was the dumbest idea I ever had (with the SA23A and Pultecs with mids). I made zero profit, got a bunch of people pissed off and it ate up all my resources. I'm glad we have stopped taking orders for them. I am still amazed and grateful daily that people trust us and wait for our work despite all the problems there have been with delivery dates. I can't even wait 5 minutes for a coffee so nothing but respect and gratefulness from my side. Once we catch up with everything there are big things coming from us and I mean big literally. A monster. |

Stay safe and hang in there Josh. I appreciate you talking frankly about the production challenges, best to be straightforward and caught up, then release new stuff. Halloween’s over, covids still here, how bought no more monsters till next October ? |

I mean, I wouldn’t necessarily consider it a negative...because of the tone. I can’t think of another box that colors quite as much. It’s not always right, nothing is always right.

Just as a point of interest here, and to try and prevent a derailing of the thread, there are 4 main transformer brands used in 1176 clones, that I am aware of.
Edcor
Carnhill
Cinemag
Sowter.
Please discuss . . . factual comments, historical connections, corollaries to others, emulation, topologies etc.
Many thanks . . . and yes, which models of Cinemags and Sowters model other transfos.
