Thanks again Drew.

I do have a multi Meyer as it happens so that first thing to do is experiment with that, which is something I have been meaning to do anyway.

Is it safe to assume that ground is negative and that on the outputs the sleeve is ground and therefore the tip is positive?

I've only been working on the sound aspect of our system so it is about time that I paid attention to those voltages anyway...

Oops... Double post...

Made some attenuators:-
 

 

Needed something to do with old phone cable?

Yeah... I'd kept that old phone cable for a lot of years, just in case of such a project

Hi,

There was a very strange and weird film done by Peter Weir, that was called "The Plumber" ... and you have to see it to believe it ... it's short, but it is a total trip ... and it makes this wiring harness look kinda ... tame!
