Walt Jung's Op Amp applications handbook available online

[xxie24]

Here is the book , chapter 6 is specially useful for audio DIY.

enjoy it!

good find.I guess I should have read todays emails because I would have known this earlier and beat you to the annoiuncement.

thanks

Excellent Find!

now add this book and you have enough reading material to last you a while,don't let the title fool you,this isa truly useful book for audio design work (don't forget to buy a few bundles of paper

I've got a good 200mb of PDFs sitting on my computer waiting for me to read them. I figure I can get through about half by the time summer session begins.

Audio Basics magazine, AudioXpress lectures, DSP and Multistage Diff Amp books, Pass Labs papers, tube amp info, and these two most recent finds...so much to get through.

what ? No tube manuals ? No Audio Basics Magazine ?

SHAME !

I can direct you to about 300mb worth of tube manuals,tube theory and tube design series in pdf if you are really serious about your education

...you did see me list Audio Basics magazine as the first item in that list, right?

As for tube design stuff, I still need to polish off Morgan Jones' Valve Amplifiers...but I would follow if you furnished a link or two. Or should I be looking in "The Big List"?

Nope ! totally blew right past and missed it

the "Big List" is pretty good for starters.actually THIS is pretty good for starters :

Damn near everything begins right there and all else is either an updated version or a variation of the Western Electric circuits.check out Pete Millette's site for more tube Manuals and links to more.Pete has a pretty extensive collection over there at his site.

there is also more to the "audio classroom" series than is available at Audio xPress but that is for later my freind.don't wanna kill you with brain overload

Oh, that happened YEARS ago. I am a graduate student after all. The great mental pop occurred about three years back when I decided to go past my undergrad.

...thanks for the linkies. Must have missed the other AudioXpress stuff when I visited the site...time to check back. Actually, now that I think about it, I might have found those classroom dealies elsewhere.

Not only is it online, you can get a paper copy from traditional booksellers now (used to be a self-published thing available only through Analog) and the production value appears to be higher. Mine is still sitting, waiting to be re-read, but I'm hopeful that it will fix some of the problems I had with the original OAA.

It is kinda funny but in many ways it is better to start with the tube manuals and work forward than it is to start with opamps then to discretes and finally to tubes which many do.
The tube guys had all this right first and even the opamp can be traced to the K-2 which used 12AX7 triodes (Philbrick Computing Amplifiers),the very same circuits as in the tube manuals are used now but with different operating points but if you understand tubes all the rest is easy and just an extrapolation.
I learned more about getting my mosfet designs to operate with improved sound by reading up on tube amp stages than I ever got from ANY mosfet literature.Weird.
All the issues I was attempting to resolve were right there in front of me years before and i never knew it.My son is an honor student in electronics so hopefully he can teach pappa a thing or two soon so i can put the aspirin away

I am still trying to get up to speed with my "glass" audio education and it is made that much more difficult by having learned the ending (monolithic) before I read the beginning chapter (RCA Receiving Tube Manual).
The horse is behind the cart and he does not want to take the lead......yet....

Those that have been in tube amplifier design or spent time getting their education in the 40's, 50's and maybe even the 60's know about this book. I have two of these in my collection, one of which is part of the MIT EE series from the 40's. This book grew out of an era of discovery, engineering, and application (WWII) which makes it one of the best fundamental reference books for beginning tube designers that I have come across. It starts with the basics (electron ballistics--

, I like physics), assuming you have collegiate math skills, and then covers many of the fundamentals of good tube amplifier design. The final edition which is still available from MIT Press even has a chapter on semiconductors, albeit from the dawn of these devices.

Check it out if you don't have it, if you do, read it and do some more problems.

Later fellas,

Back in the early seventies a buddy of mine got out of the army and he offered me an entire set of electronics manuals from the RTO course and i turned it down because it was mostly tube and radio theory so my thought was having nothing to do with audio.

Boy was I wrong !

i am astill kicking myself over that screwup in good judegement but like a lot of things when you are young,things take on much more import later in life and you can't wallow in "should have".

sheeesh.That stack of soft bound manuals was like 18 inches tall and broken down into sections for easy digestion and you just KNOW if it was a military course it was idiot proof reading !

The military takes no chances with understanding and doing a thing correctly even if you are thick headed

[reference the clamore mine with "this side towards enemy" actually printed in raised releif on the front even though the curvature should make this obvious even to a retard

just stumbled across jungs book at futurlec http://www.futurlec.com/BooksElectronic.shtml

got ben duncan's high performance audio amplifiers from my uni's library yesterday, its a really great read for most builders. not hugely technical but still great for learning about amplifiers.
