This is the new version of this ES. amp using a pair of Mundorf Supreme EVO instead of input transformers. When using coupling capacitors, the ground is not isolated anymore like a line input transformer with Faraday shield, and <1M grid risistors should be connected to the grids of ECC88 to establish a -420V DC bias voltage, which is the same bias voltage as transformer input version.
This capacitor coupled version sounds more straightforward, more transparent, but with less "transformer distortion" which is a fraction of traditional "tuby sound".
And finally, the finished amp with power supply unit in one of my friends home.
