    Ok this is the pic of the board please tell me from where to where and how I do this.I'll try myself.Trust nobody in the city I live or the entire sicily will do that.Everytime I need some help for my reel to reel or cassette deck or speakers I pack them and ship in the north of Italy

      I can't really tell from that pic. Can you take one from the other side looking toward the caps above the white resistors. A bit better light would help a lot.

        hei if I take the picture from there you will see nothing.Should I do that from the leg of the resistor closer to zd2 to the zd2 itself?Should the wire goes on top of zd2 or bottom?

          Wire from the end of ZD2 with the black stripe. I can't tell for sure which resistor is which or which end from that photo.

            thanks I'll identify the resistor from the numer,but Which side?How I can know for sure?There is any sign on the resistor?

              Here is a link about continuity testing https://learn.sparkfun.com/tutorials...ter/continuity

              If you check for continuity (basically checking for a very low DC resistance) from pin 4 of CON2 to one end of R17 then your wire will go to the other end ( where you do not have continuity). It's really really really important to get this step right - get it wrong and you'll blow the entire preamp. Please ask if this is not 100% clear.

                  Hi I have a question to check continuity on pin 4 CON 2 do I have to disconnect the connector than count pin 4(left to right?) or I have to check continuity with the connector attached with the board?

                    It's best to disconnect it to avoid any chance of a false reading. There is a "1" marked next to the end of the connector to indicate pin 1.

                    You *might* be able to see the copper tracks through the PCB by putting some light behind it. That way you can see how it really is wired up.

                        You bet. See ya in four hours October in UK is getting cold early this year.

                        I'm trying to get hold of a copy of the PCB drawing..standby..

                            Don't worry.For now I just put aside this.Someday I'll try the jumper solution hope will fix unless the owner take it back.If I do it I'll let you know

                              No continuity in both leg of r17
