    lowrey contempo 80

    Where are the octave dividers on the contempo 80? And which caps should i use? Also could i reprogram new sounds into the organ?

    Moved to a more appropriate section of the Forum.

    I can't tell you where the dividers are, but I'm sure someone will know. As for the caps, replace like with like.

    And no, there's no realistic way of reprogramming sounds.
    It's not what you play. It's not how you play. It's the fact that you're playing that counts.

          Do you have a specific reason to replace capacitors, or is this just a summary recap?

            One octave isn't working so I think that it's the capacitors.

            I wouldn't make assumptions. If you replace the capacitors and the problem persists, you wouldn't even know if you compounded the problem.

            Do you have the schematic?

              No, but I could definitely use it.

              Yep pretty sure you're going to need it.

            A bad divider will not disable an entire octave, just the same note in different octaves.

            More specific information would help. Which octave? Upper? Lower manual? Which voices?

            And there are about 300 capacitors in that model.

              The same note on every octave.

                If the 2' flute works on all of the highest notes but not the lower ones then the problem is a divider. If the 2' flute is dead on all the same notes including the highest notes, then it is one of the two top octave synthesizer IC's that is bad.

                  Every single b is silent. Even the orchestral symphonizer. On every sound too.

                    That points to IC1 on the tone generator board. One of the two top octave synthesizer IC's.
                    IC1 is Lowrey part number 991-018813-001, generic part number S2555.

                        I can't find any s555 chips online.

                      Didn't someone on the Facebook group offer to send you the relevant parts? Worth checking back on the thread over there!

                      Or was that someone else with the exact same issue?
