I'm curious what the diodes are for between the stages though. Not sure I've seen that before.
Per the description below the schematic; "The diodes in the bias network prevent hard-saturation of the transistors."
I won't pretend I'm smart enough to know how that works, but it sounds to be in the same vein of putting a diode across base & emitter to prevent zener breakdown events that degrade the junction and cause noise to build up over time.
See here: https://www.diystompboxes.com/smfforum/index.php?topic=132039.0
I wonder if those two arrangements might be considered general good practices for BJT-based preamp circuits?
