My tweaks involve a soldering iron and only the amplifier.
1. Replace the Schottky rectifiers in my amplifier's power supply with SiC rectifiers.
2. Replace the Mundorf interstage capacitors with Jupiter copper foil caps.
3. Replace the volume "potentiometer" with a stepped attenuator.
4. Replace the stock output transformers with Lundahl transformers.
