Hi,
Has anyone got a scanned copy of this book?
Or a link to where I might find one.

Best regards,
John

You don't mean An Approach to Audio Amplifier design by GEC by any chance? I've not heard of the book you refer to but a lot of research material can be found here - http://www.tubebooks.org/technical_books_online.htm its a vast stash of valve tech.

I imagine the OP means this book Andy

I don't know how HiFi Collective have come to label it as a GEC book. Their picture of the front cover clearly shows it to be Philips.

Although they list it on their website they don't currently have it in stock.

Cheers,

GJ

Amazon have it at vast cost.

mpegjohn · 23rd Sep 2023, 6:50 pm

Thank you all,
It was the Philips book I was after.

Yes, Amazon have it at a huge cost, that was why I was hoping someone had a pdf copy.

But the link Martin posted looks interesting.

Here you can download the book in Dutch:

Tomorrow I will check if I have this book in English.

mpegjohn · 23rd Sep 2023, 8:03 pm

Thank you Robert.

Robert Gribnau · 24th Sep 2023, 7:14 am

Sorry, but it turned out that I only have this book in French and Dutch.

I can't upload the French book because of its size (6.7 MB). If you want it, please send me a PM with your email address and I will mail it to you.

I have read somewhere that there is software to be found on the web that translates pdf-files. Not ideal but perhaps second best if you can't find this book in English.

Hello,

Does this help…

http://www.introni.it/pdf/Rodenhuis%...20Circuits.pdf

Alternate link...

https://www.google.com/url?sa=t&rct=...b&opi=89978449

This is the final (second edition) from 1965.

As far as I know (first) original edition dates back to 1954 and subsequent 1960 edition is an updated continuation of the 1954 edition. The link is to the second edition of the 1960 book.

Hello,

Forgot to say, I have the 1954 edition and if there were something/project you would like scanned, I can do it next week sometime..., however, the only thing I ask is make it only a few pages

Jez1234 · 24th Sep 2023, 3:27 pm

Those links are not working for me....

Valvepower · 24th Sep 2023, 3:39 pm

Another two to try...

If you mean the links in post #11, they work fine for me.

The first link works, but the second is a general Google search.

Valvepower · 24th Sep 2023, 4:58 pm

The second was, or should have been, a search with Hi-fi amplifier circuits – E. Rodenhuis as the first result.

Anyway, the first link works..., so, all’s well that ends well...

Terry.

Jez1234 · 24th Sep 2023, 5:12 pm

Tried several times with two browsers and they repeatedly timed out but yet another attempt got there... and I already have that one! Thanks anyway.

When looking for rare books, don't faff around with google, the best bet is to enter the details into www.bookfinder.com

Radio Wrangler · 24th Sep 2023, 5:23 pm

Both links produce seemingly the same result for me (MacOS, Safari, latest cersions)
