Default Starting out in DIY Solid state


I wanted some opinions on the route to understanding Electronics in order to do some DIY.

I have some basic knowledge of components - resistors, capacitors, transformer, transistor which I got in College as also some basic circuit theory - kirchoff/thevnin etc.

My objective would be to first understand design of simple amps like say the ESP P3A and further modify/build my own circuits of reasonable complexity/capability.

Any good books I can read or maybe youtube videos etc? Is there any math background I need. I do remember some calculus but forgot the stuff like Laplace transforms, control theory etc

Horowitz & Hill is the usual recommendation. Good clear writing with less maths than a typical textbook. After that Doug Self for solid-state or Morgan Jones for valves.

Bob Cordell's text is also quite good. There's a nice progression from simple to complex presented as a design 'evolution', among much other audio specific information. ISBN 978-0-07-164024-4.

For general electronics I'm not too sure what a good text is to recommend, mine are all 20 years or so old.

I would second the suggestion for Bob Cordell's book. I was going round in circles until I read that. It has the basic and reasonably advanced amplifier design in it as well as a lot of little details that keep popping out every time you re read it.

There's something immoral about that link.
Bob should submit one to "mother" Google.

I've got a couple of marginally useful books. GE transistor manual 7th ed, something else with lots of math nobody does anymore. h functions, a brief fad about 1970. Better stuff is right here. Read the sticky thread about the construction of the "Honey Badger" especially the PDF build document. It explains every transistor and what it does. Names thrown around like long tailed pair, VAS, explained.
Bob Elliot projects are a good start in simplicity. Real old designs are fun to analyze, too. The Leak Stereo 30 and 70 were in at the beginning of good silicon transistors, see this thread: Leak Delta 70 - Attempt DIY, Overhaul or buy another amp?
I missed all the design steps in Germanium, just a primer in how to build some thermal runaway IMHO.

Apologies. It wasnt intentional - the site did appear to be a 'reasonable' one.

How does one get to understand compensation? The poles and zeros appear too complex..
