Mu-follower vs two-triode stage in single ended amplifier with 12AX2-6N2P (PoC)

Hello I want to build a new amplifier using ECC83-12AX7-6n2Pev (all equivalent) and one 6L6GC in SE with GNF (no others please, because I have a lot of them).

I never played with mu-follower.

Can you please check if the mu-follower schematic is correct and which values you would suggest (using the above tubes)

Available AT is 320VAC so I think to get 400VCC.



Second question: what about two ECC83 in series and a 6L6GC with GNF? It gives me a much lower THD% (second scheme) and a much bigger input sensitivity: should this sound better?


Thanks
