Hi all,

Thought I should introduce myself, Im Matt and I'm a complete newbie. Ive been interested in DIY audio for a while on and off and think it's about time I started to learn about the subject properly and perhaps undertake a couple of basic projects.

Rather than spam up the forum with too many questions that have already been answered can anyone recommend some books? Speaker design and something about the theory and design of tube amps would be great. I realise all the information I could want is online, but somehow reading a book is easier for me than staring at a screen, and the knowledge sinks in faster too!

Cheers

Matt

Hi Matt, welcome to the forum.

You can find some book suggestions here: http://diyaudioprojects.com/diy-audio/d ... -books.htm

If your interest includes tubes, you can find some good PDF books here: http://tubebooks.org/technical_books_online.htm

Cheers

Hi I am Mike. I play upright bass in a couple bands and enjoy learning new things, like amp building. I am currently building a Fender Bassman clone in a 1930's Philco radio. Here are a couple pics:

What I started with:

And where I am at so far:

Its coming along nicely, but I still have a few bugs to work out. Its my first build, so some problems are suspected.

Hi, Welcome to the forum. Interesting build. If you run into problems with the chassis... check out Tube Depot on the web. They carry a number of blank guitar amp chassis. One of my projects that is now in the design phase is a guitar head amp. It is not like any particular existing design ( the folks that know me say so what is new about that). The current plans are for both clean and not clean channels with essentially the usual range of controls. Output is presently designed around push pull 6L6GCs running class A ultra linear. The clean channel will be really clean and the other can be altered to your heart's content. Power output will be modest at about 15 watts RMS clean and around 50% more when pushed.

Good listening
Bruce

Sounds like a cool project. The chassis is the only thing that wont be an issue. Its the one that came out of the radio in the first place. The biggest problems currently is that it only wants to scream feedback. I think I have pin 3 swapped on the 2 power tubes. But I wont have a chance to check that for about a week since I am out of town...

Hi theodorebarnes, welcome to the forum.

Do you have a need for a tube preamp? A simple preamp will be a good place to start and lower cost than a amplifier as you won;t need audio output transformers and the power transformer does not need to be too large.

Cheers
