i'm thinking if i replaced the D105/D205 1N5244 with TL431 and 2 resistors.
with sim, it looks improved as enclosed pic
When I've started testing different regulators for the FE, I've tried TL431 (without the shunting transistor, though) and, to my ears, plain zeners sounded better, fuller and more engaging.
Just try for yourself and let us know results, it's an easy mod .
What's the purpose of R11 (1ohm), can it be shorted (instead of having a jumper on Pin 7 of LM3886)?
It's probably better to ask this question over on the FE build thread,

I'm not the expert here, but I'm hoping someone with more understanding will reply.
For decoupling small signal and and power gndWhat's the purpose of R11 (1ohm), can it be shorted (instead of having a jumper on Pin 7 of LM3886)?
