A NEW METHODOLOGY FOR AUDIO FREQUENCY POWER AMPLIFIER TESTING

A NEW METHODOLOGY FOR AUDIO FREQUENCY POWER AMPLIFIER TESTING BASED ON PSYCHOACOUSTIC DATA THAT BETTER CORRELATES WITH SOUND QUALITY

In case of audio amplifier measuring technologies the most interesting PDF book I know, that I have just found by chance - go to
Next-Tube. Articles about vacuum tubes audio and hybrid amplifiers.
found under
Next-Tube. Design of vacuum tube audio amplifiers.

I am looking for this as usual book, which I can't find anywhere, probably because the edition is out of print.
But I could place a search query on ebay.
Maybe someone can upload the image of the associated cover.
Thank you very much.

P.S.: also very interesting is the paper already released 1957:

Some Defects in Amplifier Performance Not Covered by Standard Specifications
