I've run across another interesting old paper.

This one is titled, "Characteristics of Output Transformers", by J. M.
Thompson, of Ferranti Electric. It's a 12 page, 1.6 Mbyte pdf file.

If you'd like a copy, post an email address as before.

I'd like to say yes I want one but in 1928 a response from 100Hz to 7kHz
was regarded
as good but has no relevance today.

By about 1948, advances in core material and knowledge about
interleaving
techniques were as good as they needed to ever be even by today's
standards.
The principles behind the DTN Williamson OPT and those made by others
such as McIntosh
allowed 10Hz to 100kHz of BW, and low losses and low THD.

1928 OPT ideas may be welcome to those studying historical progressions.

1. He hasn't asked.

2. I don't have his email address.

3. A search on google groups for the author Millett in the group
rec.audio.tubes gives no match.

4. I didn't know he was an online librarian.

5. Why don't you help me get in touch with the online librarians?

A further consideration is this: Brett Ludwig said "Why don't you send one
to Pete Millett or one of the other online
librarians so EVERYONE can have it???".

Based on the responses I've gotten, not EVERYONE is interested.

Also, copyright law allows for "fair use". On Millett's site he says,
"I've found that most of the technical books published before about 1964
never had their copyrights renewed, so now are in the public domain."

I'm not so sure the two papers I've offered to share are public domain.

I think getting a single copy for personal research is allowed, but posting
it where it's accessible to the whole world may be questionable.

I don't mind the tiny bit of effort involved in sending it to those who
have enough interest to request it, so I think I'll stay with that mode of
operation.
