Building a 6SN7 SRPP preamp kit.

Installed the mod this morning. The gain is manageable now. I know the quality of the FB resistor have high impact to the SQ so I bite the bullet and use my old stock of Audio Note 0.5 Watt resistor. The SQ did not change much but the high seem to extended I need to burn in the resistor a bit this afternoon and report back. Once again thank you @paulbottlehead

When you use feedback to drop the gain, the Miller capacitance will drop a bit as well. This can be really meaningful when you put a 100K pot between the input jacks and the actual preamp circuit.
