Default Bernards various old data colour codes etc.

Don't know if already highlighted.
I have a paper copy that I made over 10 years ago from elsewhere.
Useful info, standards for transformer wires and battery radio wander plugs.
Assuming manufacturers followed it!

Great information. Thank you.
However please keep in mind that not all U.S. mfgr's. used the same color code.
I learned that the hard way 50+ years back.

I ran across several U.S. made transformers using red/blk on one primary wire and slate for the other, and other oddball combinations.

Ok Frank, I realised it is just a "guide" as I was researching a transformer and I think it was just the ht and ct that corresponded.
One of those items I downloaded a few years back to add to my pdf folder of information I might find useful one day. Currently around 2Gb now!

I have about 6.

Quite a few Bernard Babani publications are circulation on internet, but of course they're copyright, and Bernard Babani Ltd is still in business:

https://find-and-update.company-info...filing-history

Their website is still live and many of their books are still in print and available, but most of the ones in the public domain (for example of the WRH Archive), have long since been out of print. Questions about Copyright are often best not asked, but here are the archived out of print Bernard Babani titles of the World Radio History archive:

https://worldradiohistory.com/Booksh...rds_Babani.htm

The Bernard Babani Publishing website hasn't been updated since 2017, but here's a clip from it, about the company's history:

Quote:

The late Bernard Babani started publishing technical books in 1942 and from this has evolved Bernard Babani (publishing) Ltd which is now run by his son Michael Babani B.Sc.(Eng.) from our West London offices. We have specialised for over 75 years in publishing only radio, electronics and, since 1980, computer books. Recently we have added a range of computer titles printed throughout in FULL COLOUR.

End quote.

The website still lists sixteen electronics books and many other titles.

The most recent book as far as I can tell is BP775, 'Online Security for the Older Generation'.

www.babanibooks.com/index.htm

That implies that in all, since 1942 Babani's have published 775 books! They published many of Sir Clive Sinclair's books in late 1950s and into the early 1960s. Bernard Babani was an agent for the technical writer F.G. Rayer. Bernard Baruch Babani was born in May 1913, and died aged just 62 in October 1975. What a remarkable man he was, and what a remarkable little company, still in existence after 81 years. Long may it continue.

Hope that's of interest.

That's a very interesting overall view of Babani Publishing.
I know my bookshelves have a fair number of their publications on them.

When I first became interested in electronics in the '50's these books were always a source of information when constructing almost any radio or audio related item.

I've just tried that index link, but for some reason, all I get is an internet error code.

. . . Hopefully this collection won't suffer the fate of some other ones but I've downloaded all those currently available just in case!

Until circa 2000, US copyright law used to differ from that of most other countries in that you had to file a copy of your work with the Library of Congress to get US copyright protection, and many people didn't bother going to the expense. That is why many US-based internet sites can legally host published material that is in the public domain in the US, but is still in copyright outside the US. The US is now broadly in line with the rest of the world, but not with retrospective effect.
