Title: Bi-polar AC Adapter ???
Post by: jflam on April 20, 2004, 03:19:05 PM
In the Anderton EPFM schemo:

Can I connect the negative and ground wires together??? If I do that, should I ground the chasis as well??  

I want to use dc jacks to connect my effects, not the three-pin Molex connectors he calls for. This will be possible to achieve if I can to the above, correct?

I'm not sure what you mean here, but any bipolar supply must have 3 wires, positive, negative, and ground. Shorting any of these 3 to any others is fatal to the power supply. If you must avoid molex, you can use a small stereo jack and plug (tip negative, ring positive, sleeve ground for example).
