Dear All,

I have received an Email from Wilfried DL5SWB reporting that the
link no longer works from my web site to the Philips 3C85 data
sheet previously at:
http://www.acm.components.philips.com/pdf/3c85.pdf

Following their use by David Bowman in the G0MRF 136 kHz Power
Amplifier, toroidal cores of Philips 3C85 material have become
the preferred core material for many LF experimenters.

I found on Your Website a link to download the 3c85.pdf. But it
isn't still available. I guess this type of material will not
produced any longer by Philips or now by Ferroxcube. I got the
new catalogue from http://www.ferroxcube.com without any 3C85
mentioned. There are more new ones. Perhaps You know, what new
material is good for 136 kHz.

It would be nice, if You could send me the 3c85.pdf by eMail.

I wonder if anyone has stored a copy of 3c85.pdf that they can
send me?  If so, I will forward it to Wilfried.

Also, does anyone know a suitable alternative to those magical
3C85 cores having a diameter of 25; 42; and 58 mm?

Regards to all,
Steve GW4ALG
