Re: Dumble video/sound clip reference, real Dumbles only please

Max, You can clearly see the slope resistor and that the midcap is the same length as the bass cap. This indicates .05uf. No way that the midcap is a .01, it is too long.

This one took me 6 weeks to finish, and best of all,it worked right ...
