76
77	This BOM is for one (1) PCB. You must order two (2) to populate a stereo kit
78
79	Parts in blue are from My_Evo Rev. A mod, that mod is applicable also to the My_Ref FE and is a further improvement in measured and perceived performance.
80
81	Parts in purple are supplied with the SMD Option.
82
83	Parts matching it's not necessary, though the amp will benefit from matched HFE for BD139/BD140 and 1N5244B. All resistors are 0.1% so no matching is needed at all.
84
85	(*) Cerafines (50V minumum) have an open and direct sound, similar to Black Gate PK, while KZs are also similar to Black Gate in timbre but more laid back. Silmic II Black/Gold will sound very good too but different, very musical and inviting but lacks a bit of detail and sparkle, soft bass. You can swap among them to tailor amp sound to your taste.
86
87	(**) Amtrans are more neutral and refined than FKP2
88
89	(***) Auricap XO 600V is the general recommendation but if Isabellenhuettes are used in R3 the 200V will be a better match. The 400V sample I've tested was the best balanced one but sounded sometimes harsh.
90
91	(****) Vishay Z-Foils are for the ultimate cost no-object My_Ref FE, Z-Foils are richer, more neutral, refined and detailed. RN55 are more laid back with less sparkle. Best positions for them are probably R12 (first) and R10 (second)
92
93	For US partecipants, Sonicraft has way better prices than PCX for Mundorf Capacitors, particularly for AGs.
