I want to listen to hearts. Just like they pretend to do with a real stethoscope.

That's interesting. Do you have a large collection of them?

I find the  ' drs  ' stethoscope ' is no good to hear a heart ,

as it doesn't improve the sound .

An amplified microphone will give marvellous rendition of any heart malfunction. 

But , that OLD mechanics stethoscope Will find that squeaky bearing every time .

"SQUEEKY Wheels get attention first. You can pick a "Shot" bearing by when it knocks. Listen after you change the filter and before the oil gets there, for a start.. Short a plug out to get a big end knock. Main bearings knock under load..  Nev

I knew a gun Holden mechanic in the late 1960's, who could pick up a worn big end by "floating" the bearing load. He'd run the engine up to about 2000RPM, then lower and raise the RPM just a 100 or 150RPM each side of his chosen throttle setting. It was interesting hearing the bearing knock, as he did this.

Yep, the Iowa result reinforced to me that the republicans are in big trouble. To get onto the ticket, you need to support Trump. But supporting Trump will cost you 5 percent of the real vote.

Gosh, I hope that this is correct.
