Hi Sten and everyone:
Thanks for your answer, but I am sure about R613 and also I can see in my
burned resistance the color Brown or red in the first line and black in the
second, it seems that the 2 resistances are the same value, As I said they are
located on the horizontal circuit board with the audio power out and very near
the fuses, they are in the line of the complete wave 34-0-34 AC from the trafo and they go through this 2 resistances directly to
the rectifiers diodes in the vertical rectifier card. I had to change also the
rectifier diodes and 1 swithching transistor, so now
the receiver is working if I shunt the resistances, but I really would like to
put the real values because I'm sure they are a kind of protectors.
I'd like to get the service manual, but now I am worried they won't match my equipment. Maybe they have different numbers, they are very clear printed in the circuit board. Could you check again please? Thanks for your help in advance.

: R612 = 180 ohms 2W
: R613 ?? Are you sure
: R618 = 150 ohms 2W
: If you get the Service Manual you can also found out why those resistors are burned.

: : Could someone please tell me which are the
values of this resistances, R612, R613 ? They are burned in my receiver Sansui
5050 and I am not able to see the color code. They are a resistances protector
for the switching circuit for the rele of the
