L'espressivo+, A Moderately High End Parafeed Amplifier for Headphones

A version of the L'espressivo using Electra-Print output transformers, Jupiter parafeed capacitors, and 7KY6 tubes. The build schematc is very similar to the schematic on the L'espressivo build page. There are two major differences. The first is that the power supply, which is shared with the S3, uses a 5AR4 tube rectifier, a custom Electra-Print power transformer, with a cLCRC filter with the input chke also being custm from Electra-Print. The two filter caps are Blackgates. The second difference is that the transformer is connected with a Western Electric connection (with the transformer return to the cathode), so the tube is biased via a resistor.
