Chris Brady
has done an excellent job documenting many modifications to his H.H. Scott 299-C integrated amplifier.

Note how Chris measures and documents (complete with before-and-after frequency response and distortion graphs!) several modifications including:

Preamp and Tone Circuit Bypass Switch
Open-loop Performance (Elimination of Negative Feedback)
Conversion from Pentode to Triode Output (significantly less power, but also lower distortion)
Additional Bias Adjustment potentiometers
Noble precision Volume control potentiometer
