If Reverse Polarity Means Positive Center then say that?

Post by emergere » Sun Jul 12, 2009 9:15 am

I've always been a little electronic phobic despite my many attempts to grasp the nature of it. Kind Even after I built a few projects I still don't get the basics like series parallel. So it should be clear. It would be clear if I could figure it out but I can't. Please make it simpler to understand.

Does anyone know which cable I want to get to power a Radial Tonebone trimode with 15VDC 400mA, center pole positive with my pp2+. I am guessing it is one of these to narrow it down: ppy, ppeh24, diamond pp2+ 18v for memory lane?

There is no 15V output from the PP2+. For that, you'll have to wait until Pedal Power Versa is released.

A reverse polarity cable means that it is cross-wired so that it reverses the polarity. The PP2+ outputs are specified as center negative, so connecting them with a reverse polarity cable results in center positive.

Thank for letting me know. Any idea when the Versa will start shipping? The buzz is starting to hum.

With the PP2+, could you use the PPY cable with one connector plugged into a 9V output and the other into a SAG output set to 6V? Yeah, you'd need a voltmeter to make sure it was set to 6V, and it'd be a little risky should the knob ever be inadvertently turned up, but could that work?
