Pre amp schematic

[HKC]

Does anyone out there has the "Precision Passive Pre-Amplifier" schematic and pcb layout published in the Audio Amateur by R. March in the eighties?
Thanks

I did some basic checking for you (thanks), www.audioxpress.com, back-issue list audio amateur 80's, there is no article "Precision Passive Pre-Amplifier", but there is a Marsch pre amp mod article.
I suggest you clarify exactly what you need and order the back issue from AX.

You are probably refering to the March 1980 Audio Amateur article by Richard Marsh titled "A Passively Equalized Phono Preamp." Back issues are available at http://www.audioxpress.com
