My tweaked audio gears
Some of my works related to my present hobby. When I was young my hobby is repairing my old american V8 engine cars, my classic Duo Glide Harley Davidson, BMW R60 motorcyles. When I realized that I can't  continue spending money with this things as I am getting old than I changed  my hobby to soldering gun works for audio gears tweak in order to keep me bussy at home while I can enjoy a better sound of music by this improvement works.
