Try 'The art of electronics' by Horowitz and Hill. It's a classic work that covers a lot of ground.
Also I recommend 'tube cad journal' on the net by John Broskie, this is proper electronics but not mired in jargon and maths.
Elliot Sound Products web pages are excellent.
John Linsley-Hood wrote for a number of magazines and published books on schematics for audio components, including:
- The Art of Linear Electronics (Oxford, Butterworth-Heinemann, 1993)
- Audio Electronics (Oxford, Newnes, 1995)
- Valve and Transistor Audio Amplifiers (Oxford, Newnes, 1997)
