I was working with some 1/4" aluminium plate.

I was having a lot of problem working it.

My tools were a small cold cut saw ,flap wheel on a grinder and some hand tools.

The aluminium seemed to smear instead.of cutting. Is there better tools or techniques to follow to remove more metal.

What seemed to work best with .h poor technique was to chamber both sides and then remove the peak formed. Keep the contact area to a minimum.

Any decent electronic supply places open on Saturday.

I ordered a type m 5.2 v power cable and I guess I needa type H.

I need it tomorrow.

Any places local that would be open Saturday?

My computer speaker are twomping.

​

Is there a youtube video that shows how different failure modes on a amplifier would sound?

​

Im guessing a capacitor with the repetitive thumping.

​

Figure the sound coming out is a diagnostic tool to help find the failed part..
