Intereted in designing and building my own tube amp. Can you guys recomend some essential reading materials to get me started. Please recomend any other bookss or articles that yout hink would be highly beneficial but may not be considered esssential.

I have never deisgned or built audio equipment before in my life to give you a frame of reference on my esperience.

Hi danny,

welcome and have fun ;-).

I think, one of the most important books is "Valve Amplifiers - Third Edition", written by Morgan Jones (Newnes / ISBN 978-0-7506-5694-8).
This book is a complete guide to valve amplifiers...

You can also download the U.S Navy "NEEDS" modules. Mod. 6 contains a detailed guide for tubes.
Take a look on this thread for further information: Neets modules.

I hope that was a little help.

Bruce Rozenblit's Audio Reality (20$ at his sight Transcendent Sound) and Tube Audio Design.
Alos check Rainer zur Linde's Audio Valve Amplifiers.

If you want to design it this is a good place to start IMHO.

http://www.freewebs.com/valvewizard1/se.html

This guy explains load lines better than any other site I've found. He makes the important differentiation between reactive and resistive loads which most other explanations ignore. I know when I was reading and learning (knew NOTHING about tubes 4 months ago) this site was the one that filled in all the missing gaps, at least for me.

After about 100 hours of reading I can now design my own amp! Good luck with your project. Your first decision will be which topology you choose. Push-pull? Single ended Triode? Lots of choices! Go for it. Good luck and good listening.

If that site is too complicated I'd recommend googleing "vacuum tube amp design" or "tube amp schematics" or simply "how vacuum tubes work" and you'll find more information than you need. It may take awhile to learn it but if you're patient and you understand basic math you can learn to design your own amp. Or you could used Bruce's Oddwatt circuit which is a killer amp that is very simple to build (relatively speaking).

Here are some of the DIY Audio books I've got in my library:

As noted already, the Morgan Jones books are great.
Cheers

Hi Danny:

You might want to take a little different tack. The book "Guitar Amplifier Preamps" by Richard Kuehnel is a great introduction to basic tube operation and because distortion is so important in guitar amplifiers, he spends a lot of time talking about how distortion enters your design and how to avoid or exploit it under various circumstances. His discussions of amplifier bandwidth and high and low frequency frequency roll off are also very good. He has a complementary book "Guitar Amplifier Power Amplifiers" covering high power output stages. Even though both of these books have "Guitar Amplifier" in the title, the information contained in them is widely applicable to good high fidelity amplifier design.

The Morgan Jones "Valve Amplifiers, Third Edition" is also ok. His discussions of the different types of tubes stages are pretty good and this book has a great discussion of tube technology. Just stay away from the chapter on power supplies; it has some "problems" :? .

And definitely try some of the online stuff. There is a lot of information on the internet just waiting to be used.

Hi. Danny.

Since you've already known & told us you are a 'newbee", why worry about "designing" yr own amp?? Just make a search for some easy & basic schematic & build it to get more insight of DIY electronics. This can be a lifetime hobby, like fishing, So take yr time to get yourself in shape.

If you ask me, my reference books are: RDH (4) - Radio Designer's Handbook 4th edition.(1,433 pages). This handbook teaches you the basic electronics theories & application knowlege.
I find it extremely helpful in my DIY audio hobby despite my formal education & business is electrical engineering.

That said, music listening goes above & beyond audio electronics. One got to love music to make this DIY hobby a livetime enjoyment.

I was thinking.... Since there are a lot of tube-noobs (newbies) that end up here (just like myself :D ) on this forum wouldn't it be a good idea with a forum section for "Getting started with tubes" were we could put threads about literature and suggestions for really easy schematics and essential safety know-how, and maybe how to minimise material damage to your projects and other topics relevant to your start with tubes and tube-electronics? (The dim-bulb test should definitely appear here.)

I would suggest starting with a good electronics textbook and a physics textbook, these can be a bit heavy reading but a basic understanding of electricity and basic component-knowledge helps a lot, at least that's my experience.
