The 6EM7 gain section does not
lend itself to DRD or Full Monkey
as it's Rp is too high.
Above is a directly coupled circuit.
For FM or DRD use a 6J5 as the gain tube
and the 6EM7 power section as the driver.

  Gluca
  
  Looks good except for one thing.
  The B+ is way too low.
  The CCS can only swing about 25V.
  Make the B+ 350V and replace
  the CCS with the interstage
  and all will be well.
  Slightly higher ouput impedance
  and slightly less linear but nice.

    Actually I am running B+ at 380V and voltage swing is good for my headphones and as line driver. Yes, you need more headroom as driver stage. I must admit I was surprised by this small tube, damn good sounding tube!
