Default Electronic Engineering April 1949

Hi all,
Does anybody have a copy of Electronic Engineering April 1949.

I would like a scan of the article on Leakage inductance if possible please.

I have checked the American Radio History site, and this is one of the missing (of course)

John

The same author wrote this article a few years later?

You should be able to get a photocopy from the British Library via your public library. They do charge of course.

Hi John, I'll see if I can find it and do a scan
Crowhurst was a prolific writer on transformer topics and he usually provided well researched nomograms as a design aid. Lots of articles from him in EE, but Audio Engineering was not such a popular magazine and very few copies survive for research, A great pity.

Interlibrary photocopy request from the British Library.

Otherwise the IET library?

If you have any difficulties with local library services, you could try the National Library of Australia on-line copy service: https://copiesdirect.nla.gov.au/home.

“Electronic Engineering” appears to be available: https://catalogue.nla.gov.au/Record/...et=1&max=10799

I have used this service several times. Charges are reasonable when they have the original, and basis one or two comparisons, lower than doing the same from Linda Hall (Kansas City, MO, https://www.lindahall.org/), who seems to be the “go to” resource for this kind of material. There is an additional charge if NLA has to source from a third party library, but it does seem to be part of a large network with wide material availability. Turnaround time is typically a week for material NLA has on hand.

Cheers,

Thanks again for the help all.

Ed, I would be grateful if you can find this date please.

I have a lot of scans of Mr Crowhurst's work, and they are a great reference. This is one I do not have.

Half of them seem to have come from down under anyway!
