Wow, this is the best way to destroy those switches in the long run. Simply use a fibre pen like the Ecobra 730 300 to easily get the silver oxidation off without completely ruining the silver plating like you do.
After watching, I really don't think his method is that big of a deal. Will these switches wear out after a while? Yup. But probably after several repairs and probably decades of use. Anyone still wanting to use it will just have to source new parts, which will probably be 3D printed in 10 minutes by then. Not a big deal.
I'm also looking to get rid of a high pitch sound and noise on my DX. My suspicion is that the 470uF caps on the output have failed after 40 years (based on a similar problem with a mixer I had years ago), but I'm just an amateur. Do you have any advice or guidance?
Does the noise go away after triggering all drums? There is a known problem with EPROMs that have widely different values in the first two address locations, but only right after powering up the machine, before the first trigger event.
If they are working OK, I wouldn't worry about it, though it's pretty easy to reheat the solder and push them back against the circuit board.. If not, it may indicate that the switches have been pulled up, bending some of the contact wires out of shape.
Thanks, this & another comment of yours regarding the u10/11 tempo problems helped me restore my DMX. Much appreciated.
Nice work
Great video!

I am not familiar with this fibre pen. Do you have a source you can share?
We're all just doing the best with the knowledge we have, but thanks for the advice!

what is that tool you emoved the nuts called? and what size do I need?
thanks
A 1/4 inch nut driver. a.co/d/dIA418s
@@pjwhite42 thank you very much
thx a lot !!
Some of my switches are wobbly and some are not. The solderings seems ok though. Is that normal?
