I am more than happy about having finished some ideas that have been bugging my mind since a while. I never liked that "tone" knob, so I decided to "put it to rest", and move the "speed selector" to that place. The less buttons, the better. All the board's parts are actually still in place, however the "tone" potentiometer's lever was chopped, and the "speed selector" was heavily chopped/modified. The rest is done through a few 3d-printed parts, including new buttons for volume/pitch. Same applies to the Start/Stop button "flush" install, which is a modified Sanwa button with 3d-printed FLAT cap (on the quality caps like Sanwa, You can take the cap off). I never liked the arcade buttons' round top. It's not all finished yet, just a dry-build. There's some more parts I made, the platter and the headshell, but I have elaborated on these more than enough in previous posts...
I had intended to cover the whole thing with a decal in the end, but the more I actually worked on it, the more I liked the idea to keep it look "stock, with an unflashy twist" (even though I like that "rough" or "used" look of the Start/Stop, I believe it needs a final paint job).
Little video, showing the functionality (and some really horrible scratch skills):
Longer version which also shows how You can install a platter within seconds (grab the ring from the top, not from the bottom):
One pole of the switch handles the speed, the other handles the torque - different speeds (apparently) require different torques.
Ah, so one controls voltage, and the other one currency? I finally understood why there are 2 switches visible in Your circuit diagramm (which I'm extremely thankful for).
