Component(s)	Original Value	New Value	Comment
C22	180μF/400V	270-330μF/400V	Significanty less hum on headphone output. Max length = 36mm
C23,C24	10μF/400V	22μF/400V	More delay to B+ voltage, protecting tubes after switching on the amp. Max length = 36mm
C7,C8,C11,C12	10μF/400V	15μF/400V	Optional - gives a bit more room. Max length = 20mm
C31,C32	3300μF/10V	10000μF/10V	Higher and better filtered DC heater voltage. Max length = 36mm
R64	0.47 Ohm	Short (0 Ohm)	Cut off a pin of a resistor, bend it twice
D7	DB107	DB207	Lower forward voltage drop. Required for driver update.
C34,C35	220μF/16V	220μF/16V	Optional - gives better high frequency filtering of bias reference
C13,C14	220μF/16V	470μF/16V	The low ESR is very important
C33	220μF/16V	330-470μF/16V	Better low frequency filtering of bias reference
