Hi Bob,
I would really appreciate your opinion about this type of compensation, in some way unique (as much as I know). OITPC - Output inclusive TPC (not TMC)
I used this kind of compensation in all my amps last few years, it is quite robust, not critical in components tolerances and easy to get between 70 to 80 dB of the Loop Gain at 20 kHz.
Have you included Current Feedback Amplifiers in your second edition book? I have first edition and waiting for second one.
best wishes, Damir

Hi Damir,
I'll have to look at your schematic in detail, and I'll get back to you. In general, output inclusive schemes, if they have unity feedback from the output to the input of the VAS, like Cherry compensation, at high frequencies, may not be stable, depending on details. I'll get back to you on this after I have taken a look at it.
Cheers,
Bob
That is the plan and the expectation. The manuscript has been submitted, but the turn-around by the publisher can be quite variable. I'll probably know better in a few weeks.
Thanks for your interest.
Cheers,
Bob
Hi Bob.
That's great news that the manuscript has been submitted.
Lets all hope that they are able to process and publish the second edition soon.
May I ask, who are you going with for the publisher for this section edition?

Thank you Bob. This amp built for Richard Marsh is 200W version of my CFA and using the same OITPC compensation. http://www.diyaudio.com/forums/solid-state/243481-200w-mosfet-cfa-amp-129.html#post5475488

Hi Bob.
I hope you are well and enjoying your time after completing your book. If possible can you give us all an update as to when we may expect to be able to purchase a copy.
I hope that the publisher prints enough copies so no one misses out as the must be a lot of people eagerly waiting for the opportunity to read your second edition.
Hi Bob,
I hope that you are well.
Do you know if the 2nd edition of your book maybe available before xmas as it would certainly make a nice gift.

Hi Stuart,
That is my fondest hope. It did not escape my mind that it might be a good Christmas present to some 🙂. The completed manuscript went to the publisher about 6 weeks ago. It is quite difficult to predict how long a publisher takes to get it into print, since there can be a queue of books ahead and the amount of time to do the copy-editing and composition can be a bit unpredictable. I believe that there will be some information on it at AES and it may go up on Amazon before it is actually in print. I'll be at AES NY in a week or two and will probably learn there. Sometimes pre-orders are taken on Amazon, so that might work for Christmas presents even if publication in print misses Christmas a little bit. Getting it into print before Christmas would certainly be the biggest Christmas present to me 🙂. I'll keep you posted.
At RMAF now, and it has been a great show, with some fabulous-sounding rooms.
Cheers,
Bob

Bob best wished to you for this publication. I hope you sell a million.
I'm looking forward to it.
I'm looking forward to it.
Thanks!!!!!
If I sell a million, I buy one of those sets of great speakers I head here at RMAF, many of which whose price range is in the $50,000 - 100,000 range 🙂. I did hear a couple of great ones under $20k, though.
Cheers,
Bob
Goody for you if you can.
My wife and I got a late start on retirement savings. So guess where all our money is going. Not much left for toys.
My hearing has gotten so bad there is not much point for me looking into the future.

Have fun Bob, wish I could be there, say Hi to Alan for me! I just bought his spectrum analyzer.

Thanks for the detailed update Bob
I am really looking forward to this book am I really hope it sells well for you.
Please keep us posted with any updates.

Hi Bob,
As your new book went to the publisher, probably you could find a time to look at the OITPC compensation. I would like to know if this kind (as a whole) of compensation was used before. I know what Cherry suggested, but in my knowledge it was never used as I described it in the thread.
Best Wishes

Hi All, I was going to purchase some 2N5401 from digikey and I noticed that they are now marked as obsolete.
Can someone please recommend a suitable replacement for the 2N5401 and presumably 2N5551
Thank you.

Mouser are stocking parts from Central Semiconductor - anyone here used any?
You can also get them in surface-mount packages from a variety of manufacturers e.g. the DZT5401/5551 from Diodes Inc.
