Reversing 9V DC supply
Posted: 05 Mar 2013, 00:30
Hi, I looked quite a bit around the forum to see if this been discussed before but couldn't find any very relevant topics.If I'm mistaken please refer me to the older thread an delete this one .
I built a Ge Fuzzface for a friend and he likes it a lot but asked me to make it run with the standard +9V dc supply, if possible.
Of course the circuit is with PNP transistors and positive ground,so I was wondering if there is a standard layout for reversing the polarity from +9V to -9V and add it to the circuit so that it works fine as is.I suppose there should be an op-amp to do such a thing along with some filtering and regulation.
Thank you for your help!
