    deep end of depth



    Still reading up and looking at both the PAS Manual and the Schematics.</p>

    </p>

    I
    just wasn't sure if the PAS manual has some missing pages ... after the
    last page, it seems like it could still go on for another chapter.</p>

    But many, many, many thanks so far for the PAS manual. Very cool reading.</p>

      I know what you mean, but that's the complete manual. 2 parts, 38 pages and 121 pages respectively.

        Hi guys ! </P>


        I would like tohelp in this community too. I am an owner of a D85, and I'm looking formodifications too.I am a sound engineer and electronic technician (not engineer, I studied only 2 years electronics, but it helps, anyway !). I need informations to a better understanding of these beasts !</P>


        Ifsomeone can share again thePASS manual (or send it to mewith yousendit or equivalent)it could be great !The link for downloading this manual doesn't work, because it was shared probably only for few days.</P>


        Thank you !</P>


        PS: I am searching too the schematics of the D85 (and others E70/E75 eventually)too if someone have it.</P>


        </P>

            I think this thread fizzled out because it'll be hard work to mod the E70, plain and simple! And I was the one who started it...[] I certainly haven't forgotten about it, but I've got a lot on my plate at the moment, so it's on the back burner for now.
            </p>

            I'm also the one who scanned the PAS manual, but here's the problem: I had a hard drive crash and lost the PDFs I made. FlametopFred will hopefully still have them - maybe he can upload them again somewhere? </p>

            Fred - are you there? </p>

            Regarding the service manual - that's a different beast with lots of fold-out schematics, and I only have an A4 scanner. We both (Fred &amp; I) picked them up on eBay...

              that's a shame about the crash...</p>

              anywayz, i've been looking on ebay for a service manual</p>

              is this the pas manual listed here? seems to have a different title than yours:</p>

                  thanks clavier!</p>

                  i'll read this while i wait to find a service manual,</p>

                  i doubt i'll come up with much for mods until then ...</p>

                  </p>

                  meanwhile is there anywhere to get repair parts for this?</p>

                  i fixed a noisy bearing in the leslie, but it really needs to be replaced,</p>

                  also need some of the bulbs for the switches etc.</p>

                  i'm sure these share the same parts as other electones...

                    Not only do they share parts with other PASS Electones, but many parts are simply of the shelf electronic parts, excepting some of the IC's. One of the main differences between the GX-1 and 'lesser' Electones is that the GX-1 was built with fully discrete components while the others utilized integration. Other than some IC's though, most parts would be available through Digikey or the local hardware store. The bearings in the rotary are likely standard ABEC 5 bearings, probably the same size a skateboard uses. Those bulbs might be a smaller version the kind you see on christmas lights. If you remove it and compare to various replacement bulbs at a hardware store you might be able to find it there. If not, try Digikey.

                      Great stuff! I just became another proud owner of the Yamaha E70. And I do have a CS80 too. </p>

                        Those are great ... I had never come across that before, and just what I am looking for!</p>

                        Mostly I just need time ... or money to hire an electronics person. Is there a contact for that E-75 user?</p>

                            Me too. I want to do the same, but when I do it, I think I am going to use sliders for mine.

                              coolness another one bites the dust ah

                              that mod is cool and sounds pretty simple. </p>

                              i'm thinking the preset drawer is a better place,
                              but it's a good point about mucking with the controls while playing...
                              i like the sliding cover though. initially i was thinking in terms of midifying and adding patch control/storage via uc or likesuchas
                              but then, i'm a bit biased that way, being a programmer and midiboxer.</p>

                              meanwhile i still haven't found a service manual, though the pas doco is very interesting...</p>

                                Me three![] I'd prefer sliders too, but I think a panel to sit up in front of the music stand is the way I want to go. I definitely think this guy's method is the way forward though - it's much simpler than the method my engineer friend originally suggested, back at the start of this thread. I had no idea waveforms could be selected this easily - woohoo!</p>
