Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. U: µF,
pF: µµF 50 WV or less are not indicated except for
electrolytics and tantalums.
• If a numeric value of capacitor is a decimal fraction, the
preceding zero may be omitted.
(For example, .1 expresses 0.1)
• All resistors are in Ω and
