The Simple EL84 PP version 2 (on steroids)

This is the second version of my first DIY audio project. I changed the Driver tube to 6E6P strapped as triode with CCS load (IXYS 10m45s - 15mA).
Current sinks LM317 at EL84 cathodes it not grounded but connected to a -24V negative power supply. That gives more gain, less distortion and gives also much more headroom for the output stage.
The coupling caps are 0.22μF PIO JENSEN. I' ll try the russian teflons in the next few days.
This tube amplifier simply rocks.
