  • Rodgers 110 scarborough puzzles!!!

    Again I need the kindness and expertise from gentlemen of this forum.

    I got the organ from a church (again). It was used with the church speaker system through the tape recorder output for at least 6 years. That's all the gentleman who gave it to me knows since he associates with the church's band 6 years ago.
    He did not know there are internal speakers, until I open the back with him. The internal speakers consists of two separate channels (I think at socket 1 and 2 as in pic 1) with 1 12", 2 6 x 9, 1 15" and 1 Leslie.

    Since I got it, the only way I can hear its sound is from the headphone, but cannot be adjusted louder. The sound from headphone comes from cable of socket 2 as in pic 1. When swapped with socket 1, it sounds very little like nothing. So I assume that something wrong around socket 1.

    When opening tapes around small wires of socket 1, there are many cut wires, connected to nothing as in pic 2 and 3.

    There is another strange thing (at least to me): the four wires blue, purple, brown and yellow from socket 1 connected directly to the wall of the organ as in pic 4, together with a big and around 25' gray cut cable!

    Can I just reconnect the cut wires?

    What I should do to use the internal speakers?

    I have a Leslie 110 and a 51C. How can I use, say the 51C with this Rodgers 110?


    Thanks in advance,

      Definitely yes. I am going to reconnect audio wire and hope to get the speaker system back.

        The speaker system is working now and the leslie as well. Now after turned on and a key pressed, the organ's sound is loud right away even though the expression pedal not pressed. Can someone give me a hint of what might be the cause of it? Is it related to the amp, or just the pedal?

        thanks,

          Hi,

          Your organ likely has a blown light bulb, which is tied to the potentiometer on the expression shoe. The brightness of the lamp, controls a LDR for each channel. On the mixer board you will find a big rubber cap. Pull it off, and you will see what I am talking about.

            AV,

            I don't see any light bulb around the expression pedal. Do I miss something here?

              Another issue is the sound from headphone jack cannot be turned louder ...

                Here is the board AV was talking about. The rubber cap is just above where it says "Preamps" in the photo.
                The lamp is soldered in. It is a #24CS. 24volt, .02 amp, Rodger's part number is 1460-013.

                  td and AV,

                  The light bulb looks ok to me. When pressing the pedal down, the volume gets louder and the light gets dimmer and dimmer and goes off. Do I still need to replace it? I see 4 blue round knobs around the bulb and wondering if they are related to the bulb?. Are they adjustable?

                    Those four thumbwheels might be the volume controls for the four unit stops. Try holding down a note on a flute stop in the great while adjusting the wheel marked "flute." You might find that it has been turned up much louder than needed since the organ was used in a church and they were evidently using some remote speakers instead of the console speakers.

                    If that works, do the same thing with the 16' pedal stops (adjust the "pedal" wheel) and the 8' swell trumpet or other stop (adjust the "swell" wheel) and the celeste.

                    Good luck!

                      John,

                      Yes it works, the whole volume goes down when expression pedal not pressed. But at fully down pressed, the volume is not up as it should be compared with other organs. The interval between max and min volume is not like other organs. The other thing is there is nothing can be heard from headphone because the whole volume was down.

                        Be sure to replace the cover over the light bulb assembly.

                        Does this organ have a "Practice panel" for the headphones. It would have a balance control, speaker switch and reverb control along with tape recorder outputs.
                        If it has a practice panel then it should be plugged into the "accessory" socket on the output chassis.

                          This is the way the organ was used before moved to my place. The accessory is at the back on the down socket. The up socket outputs go to speakers.
                          I think the amps is defective that's why the church used the tape recorder output to the external amp to play the organ.

                            Meaning the practice panel (it) should be plugged into the "accessory" socket?

                            It's a (possibly) long hard road to undo someone else's undocumented hacks.

                            If there was something wrong with the amp, you would still have no sound.

                            I wonder what would happen if that cut grey cable (photo #4 in your original post) was put back together?

                              The gray cable in pic 4 from my first thread is connect to nowhere. It is removed now. Because one end of the gray cable connected to the speaker wires, I think the guy who did it wanted to use the external speakers and then he or someone else figured it out they they can use the external amp then they stopped.

                              The amps still working but not as good as it should be. That's why they did not want to use it anymore.

                              I attach some pic to explain the connection from the accessory socket to the practice panel
