"Operazione Goodnight" Headphones Amplfier Using Vacuum Tube ECC82 ( 12AU7)

My  Project about a Vacuum Tube Headphones Amplifer for my Philips Fidelio X1:

My Tube Amplifier and My Headphones Philips

My Headphone Tube Amplifier 
Tube used for amplifier is a ECC82/12AU7 followed by a discrete Class A BJT Buffer
The First One mede uses ELNA Cerafine Audio Capacitors.
The Power Supply is my Board made by a mix of  Bust and Buck Switching Converters from main 12-24Vdc
So  From DC Supply we can obtain: 200Vdc for Tube circuit, 30Vdc for Buffer Circuit, 6,3Vdc
