hi every body...
i have a radio made in east germany model..AT560 GWK3..it's an AC DC radio
the thing is the selenium rectifier is missing...so i tried to replace it with a silicon diode
but the problem is when i'm applying 110 voltage and measure it at the end of the diode it reads 150 dc??? why the voltage increases?and when i connect a resistor in series with the diode (i used different values) the voltage remain 150 dc??
is it because there is no load on them(i did not connect it to the radio circuit)??
below is the radio schematic...... i appreciate any help or advice ....
thank you very much
