Partlist

Resistors are 1/4W 5% (or better) and capacitors are 5mm pin-spacing, unless otherwise noted.

Part Value Qty Notes
C1, C6 10n 2
C2-C3, C5, C10-C11, C15-C16 100n 7
C4 4.7u 16V 1 2.5mm spacing, electrolytic
C7-C8 470p 2 ideally should be film, but ceramic will fit better. Use C0G/NP0 type
datasheet claims 2.2nF but in practice 470pF were always used. 2.2nF will sound too deep.
then again, your mileage with 6581s may vary and you might want to experiment with different values.
