The manuscript is with the publisher. It was submitted around mid-august. It is always difficult to predict how long it will take for the publisher to get it into print. I think we are looking at sometime in the first quarter of 2019. I sure do appreciate your interest and patience 🙂.
Cheers,
Bob
Hi Bob,
I checked the Routledge site for Focal press :
Focal Press: Audio - Routledge
There are books planned for 1st April 2019 - and listed - but yours is not listed. Is it possible that there may be a glitch in their system - and they have failed to sequence it into their production ?
Regards,
Shadders.
Hi Shadders,
Thanks for your interest in my book. Based on my current information from Rutledge, I do not think it will be ready by April 1. I'll keep you posted, and I think I will have a better idea of the publication date before the end of next month. I am working very closely with the publisher right now to get it into print as soon as possible.
Cheers,
Bob

Bob,
I, like many others, sincerely appreciate the hard work and experience that went into the first edition - let alone the production of a 2nd ed. in response to comments, feedback, minutiae & errata, detailed expansion of certain themes etc.
For myself - I can't wait to place the pre-order when the timescale is known.
Best wishes,
Martin

Hi Bob,
Thank you for the prompt reply. I think we are all enthusiastic to obtain a copy as soon as possible - so we do appreciate the work you have put in.

Does someone have a list of the different ways people have tried to improve Cordell's error correction circuit? I remember Edmond Stuart had some modifications, and I thought there were some other ways floating around here on DIYAudio.
Upon careful reading of Bob Cordell's 1st edition, I cannot find any mention of "Cordell's error correction circuit." Would you please cite page# and type out a brief quote, so we can look it up for ourselves and discover the thing you are talking about?
Possibly could it be (that professor)'s error correction circuit which Bob copied with full attribution, in link #6 of the "Published Papers" zone of Bob's website? Neither Bob, nor I, nor the professor, nor any rightthinking scholar, would call that "Cordell's error correction circuit", so it seems likely you refer to something else entirely.

My mistake. Cordell used Hawksford Error correction in his error correction circuit.
Has anyone bookmarked some of the attempts others have made at improving it?

Hi Keantoken,
Giovanni Stochino Linear Audio has analysis and examples of Hawksford's Error Correction (Vol 7) and Bob Cordell's version (Vol 8) which Giovanni calls Enhanced HEC since it is a variant. According to Giovanni Bob has added a RC LPF upstream of the voltage summer to roll off the positive feedback so there is no need to limit the bandwidth of the error amp as in the original HEC..
BTW Vol 9 has part 2 of Vol 8 but is on a Black type Feedforward amp and not HEC, it's the 3rd generation design, the first was in Electronics World Oct 1994.
In the refs for HEC are Bob Cordell, Bruce Halcro Candy (US6052027) still in production I think, Jan Didden, O. Popa, and E.Stuart.
