4th Ed. of Audio Power Amplifier Design Handbook (Doug Self)

[nickds1]

Hi,

Is this worth getting? I Have the previous ed., but am not especially bothered by class G.

Ta,

[Praise!]

Incidently, I had a look at the 4th ed today. I have the 3rd ed too. I didn't buy it; the only new materials are Class D amp and DC servo. Only a small sections on DC servo and it's not as detailed and anayltical as other Self's classical writing.
Hope this helps

Is the section on class-D comprehensive?

hmm yes DS's book, whilst doing a great service to distortion mechs., is not very comprehensive in other areas, the updates are far too long coming, and still don't address those, I wonder why it takes him so long?

Whilst a great book, I do get the impression its 'this is the only way to do an amp, my way, and if its not a blameless amp, its rubbish'

no treatise on other methods of stabilisation, nothing on other kinds of distortion: IMD, slewing types, I would like to see it as a complete treatise on amp design, sadly it falls short here.

I have just been browsing a copy: There are 2 new chapters, one on the design of DC servos (12 pages) and another on Class D (9 pages). From my untutored standpoint, the Class D section is by DS's own admission "more of a snapshot of a fast-moving scene", i.e. it's a pretty lightweight overview of the technology - no designs or anything like that, and no detailed maths/analysis.

I'll probably buy it for the corrections etc. to the previous edition, rather than the new content...
