What Oscilloscope specs for audio work, diagnosis and repair?

Dowsing only works for detecting running water, such as a leaky electrolytic. When I tried it, the rod would always point to my coffee cup.

The crystal ball is far better for troubleshooting. I use a form of "map dowsing" where the schematic acts as a map. I place the schematic behind the crystal ball, and look at the highly distorted future image. Failed components appear as soldering iron burnt areas or are marked by red circles, which is what I sometimes do to mark the schematic after I finish the repair.

A crystal ball will also work by viewing the device being repaired through the crystal ball, but it's very difficult to distinguish the original and the future replacement parts through the distorted image. However, viewing the device in a magic mirror, which reflects the opposite of what will happen is very useful. The reflection will show a smoking ruin for all the components, except the defective part, which will look perfect.

I guess I should have explained the different kinds of Dowsing Rods. Most common those made from the same material as the dowsed parts ie silicone, carbon, etc... Less sensitive to false positives and detection of things like beer, coffee, vomit, etc...

I used to have a crystal ball made by Nippon Gakki but it was unreliable and now parts are obsolete.

Leave it to you to have obsolete balls...

I had a Yamaha 650 bike, but never a Yamaha glass ball......

Glass balls are too fragile...

There must be a ball shortage in Australia:

(sorry... I couldn't resist)

In Mexico too, after that earthquake. :(
