I have a center-tap +v15 and -v15 power supply driving a phono preamp. I am trying to sort out earthing.
1. What happens to a CT power supply if the CT is connected to true earth ?
Does it blow up ?!
2. If the CT it is not connected to true earth is this what is called a "floating earth" ?
I've done the following so far - most beneficial:
1. reduce ripple to the voltage regs
2. use Rubycon ZA caps after the regs
3. use Eichmann interconnects - this has been the most striking improvement. Total removal of a deep roar when preamp (not phono) is turned up to full volume.
