Hello,
I Need help to repair a Power Supply. It is a very old device but it works very good, better than a new one so thats why i want to repair it.
It is a Resonant Power Technology Inc. RPM-101/4. It seems the same power supply is the RPM-201/4 but this has a additional Output voltage but seems based on the same device.
Sometimes if i switch on the device it works without any Troubles and don't stop working while i am working with this device but most of the time if i switch on power (it has an old one on/off mechanical switch) it make "tak tak tak" with a repeat time About 1 sec.
I already have Change the main Elkos (the red one on the picture). if i messure ith my multimeter the voltage on the Elkos in normal mode i get 48V (bipolar, there is a Center connector on the Transformator). But if don't work i see the value an my multimeter but the it crash down.
i hope you can help me to find the failure.
Peter
