New pre-amp chassis design

Apparently a balance circuit adds noise in a HiFi pre-amp. This results in two separate volumes for each channel. It was no fun to always adjust the volumes and never have the setting repeat so I came up with a solution to tie the knobs together. I machined this out of 6061 aluminum. To balance the levels I simply hold one knob and over ride the o-ring. It works really well.
