Quality Phono Preamp build and Wheatstone Bridge use.

On resurrecting my vinyl collection about 10 years ago and having tried a few inferior phono preamps, I decided to make my own. This inexpensive Moving Magnet Cartridge design exceeded all my expectations. Modern amplifiers of that period had absolutely no idea what a phono input was, so I used the aux input of my ONKYO. One of the problems I encounter was the aux input level - it expected about 4 x the output signal level of those commercial phono preamps, encouraging me to design my own. With the aid of a Wheatstone Bridge, I needed to buy only 2 costly precision capacitors.

The microphone used in this video is of my own design: https://youtu.be/01GiEWnfw8s **Please help me purchase more components for more projects/repairs.
