The circuit.
The tube can be ECC86 or 6GM8 or 6N27P.
The voltage gain is like x11.6.
The output buffer is providing like 105mA.
This is done by using a LM334Z current source.
The input and output capacitors should be of good quality.
This circuit is done for 32 Ohms headphone.
Can be used of other headphones, but I have 32 Ohm headphone.

Can this circuit works as a preamplifier ?
