HI All Thatks for all your replys! :) Now i know that it is a 10 uf 50V :applaud: Now i just need to find a S2800B Thyristor - when I test that component in my china tester it fails the test. |

Hi All I need you again :) I have found this "UA43 1AWC" who is dead.. but I cannot find any information for a replacement, or the component in the parts list. The component is at location IC1 Can anyone help me in what component that i can use as an replacement? |

The component is at location IC1 Can anyone help me in what component that i can use as an replacement? --- End quote --- Looking at the schematic above, it looks like IC1 is the Zener diode on the left side, 2/3rds of the way down. The schematic is a little hard to read, so you might want to confirm these connections on the PCB. - One trace from IC1 should go to R18 and R20. - Another trace from IC1 should go to R22(?). - The third trace from IC1 should go to R21 and C12. I only see one Zener diode on the parts list, so that looks like a good place to start or the schematic labels IC1 as a TL431. A TL431 is an adjustable Zener diode also known as a programmable shunt regulator. Scott |

It's a TL431 or a UA431. |
