I'm looking for copies of Ben Duncan's AMP-02 articles from HFN/RR 1989 and 1990. I have AMP-01 and used to have AMP-02 before I threw them away.

Also looking for BD's 'Supercharging CD' articles if anyone has those too.

Please drop me a mail if you can help.

Thanks in advance,

Hi DoctorRad -

I am also looking for the HFN article. My interest is in his discussion of "anti-resonant series resistance" as I am designing a pre-amp PSU and am not familiar with ARSR. Did you find the article?

Can anyone shed light on ARSR as used in a PSU?

Thanx!
 
I now have AMP-02 and Supertuning CD as 5-megapixel digital camera images taken from archive copies of the magazine. I'll make them available as PDFs on BitTorrent sometime before too long.

If you can get me the month and year of any HFN article, I can get library access to it without too much problem. There is also an anthology of Ben Duncan's HFN articles available for about £15, see:

This may well contain the article you are looking for if it was on of his 'Black Box' columns.
