80/80A power supply capacitors
C1 470 uF 100 V and C2 47 uF 100 V in the 60 V section; C4 470 uF 10 V on the 5 V output; C3 1000 pF 50 V and C5 2 uF 16 V in the regulator circuit.
The display supply carries 60 V DC (and 42 V DC); keep fingers off the power supply and display boards while the game is on.
