This kit is for Bally & Stern MPU boards including Bally -17, Bally -35, Bally -133, Stern MPU-100 and Stern MPU-200 *** boards.  Contains the following 32 parts that are most frequently damaged by battery corrosion.  The value in this kit isn't just the parts, it's being able to get them all at once from one source. 

  • C1, C2 - Capacitor 820pF, axial or radial ceramic (small yellow bulb or black barrel, #6 & #7 down in picture above) 
  • C5 - Capacitor 47uF, radial tantalum (small yellow, not axial as shown, polarity is right leg when viewing markings, top hole on some unmarked MPU boards)) 
  • C3, C13, C80 - Capacitor 0.1uF, axial ceramic (small barrel like two shown above) 
  • CR5, CR7, CR52 - Diode 1N4148 (CR52 optional, see note below. Smaller zener #3 - #5 above))
  • CR8 - LED Green
  • CR44 - Diode 1N4007
  • R1,R3,R24,R28 - Resistor 8.2K ohm, 1/4W
  • R2 - Resistor, 120K ohm, 1/4W
  • R11 - Resistor, 82 ohm, 2W (recommended to elevate this 1/4" off the board)
  • R12 - Resistor 270 ohm, 1/4W
  • R16, R113 - Resistor 2K ohm, 1/4W (See Note)
  • R17 - Resistor 150K ohm, 1/4W
  • R29 - Resistor 470 ohm, 1/2W
  • R107 - Resistor 3.3K ohm, 1/4W
  • R112 - Resistor 1K ohm, 1/4W
  • R134 - Resistor 4.7K ohm, 1/4W
  • R140 - Resistor 20K ohm, 1/4W
  • Q1,Q2 - Transistor 2N3904 or 2N4401 or equivalent 
  • Q5 - Transistor 2N4403, 2N3906, MPS-A92 or equivalent 
  • VR1 - Diode 1N4738A, zener, 8.2V (alternate for 1N9598) 
  • 22 Pin socket 
    U8 (pic shows machine, may supply leaf variety)
  • 5101 Static RAM (Please note Stern MPU-200s require two 5101s) *** See eBay item  273029709808
