It might be better to contact the publisher.
They are the ones who care and know the law, especially when the matter pertains to an older edition.

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

I am looking for a suitable gift for a friend for the coming Christmas.
Since he has been trying to get to grips with the common Class-D approaches with discrete parts (instead large-scale integration resp. LSI Class T/Class-D IC's) for some time, I would like to find a book that deals with repair service/troubleshooting of various Class-D circuits like e. g. B&O/SANYO ICEPOWER, Hypex UcD or NCORE® and PURIFI Eigentakt - go to
https://purifi-audio.com/eigentakt
Any Ideas where are such books available ?
Thank you very much.

You might consider my second edition of "Designing Audio Power Amplifiers" book. It includes 4 chapters that cover class D audio power amplifiers. It also includes a chapter on switch-mode power supplies, which are usually employed to power class D amplifiers.

You are not the only one interested in these closed source amps.
Good luck!
A friend of me looks for a book concerning circuit topologies from legendary developers, especially those for which no patent was granted but nevertheless with fantastic sound quality - OTOH were considered by numerous other engineers to be not well thought out.
Some examples for such topologies
