Back in April I had asked about trying to simplify a bipolar supply with a phantom rail. The big issue was that I had two transformers: one for the bipolar section, and another for the phantom section. I'm trying to figure out if it's possible to run both sections from a single transformer without any interaction between the two. My initial attempts failed miserably because of the interaction between the bridge rectifier of the bipolar section and the voltage multiplier of the phantom section when both are connected to the same secondary winding.
The phantom section is borrowed from a tube-based build I did a while back, which was using two power transformers anyway; but this is for use with solid state circuits.
If memory serves, the other big problem was isolating the 0V of the phantom section from the 0V of the audio supply section.
Anyway, this time around I'm posting the schematic I have so far. I had neglected to do that previously.
