Porfyra Audio Presents an Ultra high-end tube preamplifier based on the PHILIPS E118CC tube. The preamplifier employs oil capacitors for the cathodes and MKP capacitors for the outputs. To minimize interference and maintain signal purity, the power supply is independent from the main unit. It uses a rectifying 5U4 tube and includes stabilization threads using the LM338. High voltage stabilization is achieved with high parallel MOSFETS.
The main unit provides an on/off feedback selector switch to allow the user to adjust the output sound for their acoustic taste.
A remote control is included for volume control and to select input.
Gain: 24 dB (Without feedback) or 18dB (With feedback)
Frequency response: 8Hz to 200KHz +/- 3dB
