Notes and Comments suggestions

 

  Non standard component  (capacitors ) (inductors) resistors) values  can  make up from multiples of standard component values

  Eg  5.9 uF = 4.7uf + 1uF+.22uf 

  EG 47uF = 4x10uF+6.8uF250v preferred to Bi polar capacitor .

  Eg  .529 mH = 4.7+ .56 mH

  Eg  5 ohm  =  4.7 + .33 

   Enclosure (BOX)  25mm Medium density fiberboard (MDF) Lead lined on all internal sides 1.2 mm lead sheet
