I agree 100% with the full wave supply with Schotkys and higher quality capacitors.So many people engineers included used to discard doing anything with the C minus supply because they felt it didn't draw enough current to warrant anything other than a single diode and a couple caps separated by a resistor. All one has to do is put their scope on the C minus supply source with that simple scheme and you will see audio riding on the rail and being that audio is an AC voltage,certain audio frequencies can get filtered out in a poorly designed C minus supply.I've even contemplated putting a small choke in the C minus line.
