Hello. I’m looking for a reference guide/s on amplifier design. I’m a scientific/engineering layperson interested in building my own amplifier from a simple kit such as the world designs kt 88 amp or one of Colin Wonfor’s transistor seca designs-I’m in the uk. Obviously valve and transistor circuit design are 2 separate disciplines, so my learning progression probably needs to look some like this:

1) Acquire sound basic knowledge of principles of amplification.

2) learn how these relate to different applications in audio reproduction.

3) Learn how these relate to a specific amplifier design in detail (likely either valve or class a transistor at the point).

4) build relevant kit.

I realise that from the point of view of a professional in these areas the term ‘basic knowledge’ may imply acquisition of a 1st degree in electronic engineering, I’m aiming lower than that-just enough to get me off of the ground and to make building a simple amp a safe a rewarding learning experience.

Advice appreciated!

I'm a newbie as well and I like to browse through diyaudio's forum to learn especially their step by step guide for building the Pass Labs amplifiers. I'm not much of a reader though so I like to learn by youtube. John's audio tech is my goto now as he's very good at explaining things to layperson like me!

Phortize, there are a couple of important items I forgot to mention:
The Art of Electronics is damn excellent https://artofelectronics.net
Also, Linear Audio by Jan Didden is a fantastic set of journals - buy them all, I keep going back to them https://linearaudio.net

Be careful with diyaudio, there is plenty of misinformation there (films caps sound better than ceramic caps etc), if you are careful it can be good.

DiyAudio is a blend of pure engineering gold and mindless voodoo. There's lots of nice things to find but also plenty of nonsense. A bit of a minefield if you don't remember to put on the critical thinking glasses.

For a first project I'd rather choose a preamp (line level or phono). The problem with power amps is that a small mistake may cost you lot's of money. Line level electronics is not that critical and not that expensive to repair.

When I was in school still I built a very simple class A/B power amp according to schematics from a book (AFAIK). Although its sound was great, it blew up several times until I had no more money to buy replacement transistors and gave up. I felt rather foolish back then.

A few years later a friend wanted me to build a bass guitar amp. I built the preamp by myself but used a ready made power amp module to circumvent those problems I'd had.

The Douglas Self books on small signal and amplifier design are very worthwhile.

The art of electronics looks excellent-just ordered volume 0 of linear audio. Cheers
