Here's a layout for the Hum-Free(er) Splitter.
Been looking over it several times and I'm pretty sure that it is correct/matches the schematic.
But let me know if you spot any mistakes...
I have added some power filtering that is not on the schematic in case you wonder why there are two extra 100uf and 100nf caps compared to the schematic.
This Splitter design does not have any Phase Reversal and Ground Lift functions though...
BUT! A Ground Lift can be added by inserting a SPST (on/off) or SPDT (on/on) switch between the 1nf cap and the transformer. Meaning: add a switch that breaks the connection between the cap and the transformer (one switch for each of the transformers).
Adding Phase Reversal function is something that I expect would require a bit more circuitry (according to my limited knowledge on the subject)
