Good evening everyone,
here the photo of the repair of the power supply of Saba 9941. The great bridge rectifier is 100v/10a type and was coupled with the cooling radiator. The capacitors are large 10.000MF/63V protected by silicone hat. The fuse holders are protected in plastic case. The capacitor 220Mf is 100v, as recommended to me. Resistance 2.2 ohms is the type fused integrated. The bridge rectifier square D in 1427 was replaced as recommende to me: I was able to find the same square type, but 1.5 Amp type. The bridge D1414 is placed between the two fuses ( 2 amp ), using " sterling " tube to prevent short circuits. All voltages are correct . The ripple voltage of + -35 volts is 5% for 5 Amp absorption: very good! Now we have to see what happens when we turn-on the machine! Greetings to all, see you soon. Giuseppe.
