My build of the stereo phono preamp circuit designed by Jules Ruckebusch and featured on Recording magazine web site.
A kit of this preamp is sold by PAIA.
The preamp is used to interface a record player's magnetic cartridge
output to the line level input of a modern audio device.
I use this preamp to interface my turntable and desktop computer to
capture and digitize old LP and 45 records.
I use the free open source software program Audacity from Sourceforge to capture and edit the audio.
Audacity can encode and export mp3s with a free plugin. Information is available on the Audacity web page. The Preamp and Audacity Software both work very well.
The heart of the preamp is the 5532 op amp. I built the circuit on a
Radio Shack 276-150 multipurpose board. I reduced the width of the
circuit board with a utility knife.
The size of the aluminum enclosure is approximately
3.9" X 2" X 1" part #11957 from Jameco Electronics
I used a wall wort (power adapter) with regulated +12 volt and -12 volt outputs to power the preamp.
Schematic diagrams are viewable at the Recording Magazine and PAIA web sites.
