Audio Gadgets is software for the technically minded audiophile. The quickest way to understand what Audio Gadgets is all about is to imagine a programmable calculator designed for the audio enthusiast.

Audio Gadgets does far too much to fit in even a 21" monitor; consequently, the notebook metaphor is used to hold ten pages of audio topics. Stepped attenuators to tube circuits.

Bibliography

     After publishing an article like this one, I receive a few E-mails asking for further research sources. So here is a short preemptive strike.

Fundamentals of Television Engineering 

    by Glenn M. Glasford, 1956, McGraw-Hill

    Section 10-10: Feedback amplifiers with bilateral

    transmission between input and output.

Radiotron Designer's handbook 

    edited by F. Langford-Smith, 4th edition, 1953, 

    Electron Tube Division RCA

    Part 1, Chapter 7, Section 2, V: Voltage feedback

    from plate R.C.C input .  (Actually, the whole

     chapter is well worth reading.)

Automatic Feedback Control System Synthesis

    by John Ground. Truxall, 1955,  McGraw-Hill

    Section 2.6, Impedances

    (The most complete, but complex analysis of the

    feedback mechanism.)

Electronic Engineering 

    by Samuel Seely, 1956, McGraw-Hill

    Section 5-10: The anode follower.

    Section 6-2: Summing circuits

    Section 6-3 General operational feedback

    amplifier

Electronics In Engineering 

    by Power. Ryland Hill, 1949, McGraw-Hill

    Section 10-6: The cathode follower.

    (While not directly on topic, it is a lucid

    explanation of feedback and the cathode

    follower.)

Electronics World 

    October 1995, Page 854

    Jeff Macaulay, "Hot Audio Power"

    Very interesting hybrid amplifier.

For those readers who can read Spanish:

Amplificadores De Audiofrecuencias

    by Adolfo Di Marco, 1953, Arbó Editores

    Section 4-6: Circuitos prácticos.
