Yamaha CS80

I second this, Max!
I wish I\ufffdd find a CS80 in a shape like this in Germany, at a decent price
like that, with all that labour taken into account. I hope there will be a
good home for it.

Stephen

> You made an amazing work with your CS-80 and even if we disagree onto some
technical things I wish you can get the reward you deserve for such a work
of love. I'm in Italy and unfortunately I haven't room for it , not counting
the fear for letting the machine be tranported by someone else who's not
me...I wish also the buyer will make a responsive use of the old boy and let
it not take dust....

>
>   Electronically:
>   To start with, this CS-80 has the second highest serial number I've
>   seen, so it was one of the last ones made.  This means, not only that
>   it's not as old as many others, but that it has the last rev of the VCO
>   chips.  These are the most stable for tuning and didn't require any
>   modifications for temperature tracking, like Yamaha recommended for
>   earlier units.  The tuning wasn't bad when I got it, and since I did a
>   complete tuning on it, it is super accurate over all keys, octaves, and
>   voices.  I often have to detune the second voice bank to make sure it's
>   there because the VCOs are dead on.
>
>   CMOS:
>   As well documented on Old Crow's excellent website (www.cs80.com), the
>   CS-80 had a few design mistakes.  Almost all the digital control logic
>   is built using 4000-series CMOS chips.  These chips, especially the
>   older ones, could be very sensitive to static and can also fail over
>   time.  Luckily, these are still made today.  As recommended by Crow, and
>   other CS techs, I have replaced every 4000-series CMOS chip with new
>   ones for many more years of life.  In addition, I have put all of the
>   new chips in sockets, so if there is a failure in the future, it will be
>   relatively easy to find and fix.  Yamaha also had very few bypass
>   capacitors on the digital boards (none on one!). These caps help keep
>   the power supplies quiet and the parts happy.  I've added a bypass caps
>   for almost every single digital chip.  In addition, I added larger
>   bypass caps on each board.  This work took a lot of $$$ in parts and
>   more rework hours than I can remember, but it's a great insurance policy
>   for the future life of the keyboard.
>
>   Power supply:
>   Almost every piece of electronic gear, from stereo amps, to
>   synthesizers, use electrolytic capacitors in their power supplies to
>   smooth the AC voltage from the wall socket into nice, smooth DC voltage
>   for the internal circuits.  These capacitors have kind of a gel in them
>   that drys out over the years, degrading their performance, until the are
>   non-functional.  In old amplifiers, this commonly results in increasing
>   hum.  I have removed all of these caps from the power supply and
>   replaced them with new ones.  Since modern caps are smaller than their
>   older, same-value parts, I was even able to put larger value caps in
>   some places (larger generally equals better for power supplies caps).  I
>   even replaced the caps used in series with the headphone jack.
>
>   Keys: I removed all the keys and washed them.  There's a few really tiny
>   marks, but overall I'd give them an A.  They all feel nice too: initial
>   touch (velocity - can control volume, brightness, and pitch bend) and
>   after-touch (polyphonic pressure - can control LFO modulation and speed,
>   volume, and brightness) are working on all keys.  As most fans know, the
>   poly aftertouch is one of the keys features of the CS-80. There are very
>   few keyboards that had this (I own two other: a Kurzweil MIDIBoard, and
>   a Roland A-50, which I'm restoring - but neither feel as good as the
>   CS-80).  It's such a great and natural feature to be able to play a
>   chord and bring out one note by pressing that key harder. No keyboard
>   has been made with this for many years.  I wish someone would bring it
>   back!  I've also gone through all the key contacts, cleaning and
>   adjusting, to fix any intermittent triggering on any key.
>
>   Ribbon:
>   Besides the keyboard, the other great, rare feature on the CS-80, is the
>   ribbon controller.  This lets you bend an note up an octave and down
>   infinity to zero!  And it's relative, so you can touch it anywhere, and
>   that point becomes the starting point of the bend.  It's also great for
>   guitar/violin-like trills: press anywhere with one finger and then tap a
>   trill with another finger.  The ribbon works and looks perfect.
>
>   Cosmetics:
>   Panel: The front panel looks and works great.  All knobs, buttons,
>   sliders, and lights are 100% functionally and cosmetically.  I went
>   through every single one of the 171 knobs and 50 switches, including all
>   the little ones for the memories.  Everything does what it's supposed
to.
>
>   Case/Cover:  The cabinet is in good condition.  There are a few nicks in
>   the tolex and the chrome hardware isn't perfect, but overall a B+.  The
>   case cover is a little rougher, maybe a B-, but who cares since it's not
>   on when you are playing, but it is important to have, to protect the
>   panel and keyboard.  I've got the original casters that plug into the
>   case and cover.  They are very useful for moving the CS-80 around short
>   distances, but for big moves, you'll want a flight case.  I've also
>   replaced many missing washers that an unknown previous owner/technician
>   forgot to put back.
>
>   Stand: It's got the original Yamaha stand.  A couple of the screws to
>   lock it to the CS-80 were missing, so I put together nice replacements
>   (metric #8 bolts!).  I also added plastic furniture caps over the metal
>   feet so it wouldn't tear up my wood floor.  There's some scratches and a
>   few small nicks, but it looks pretty good - maybe a B/B-.  I don't have
>   the fancy carrying bag for the stand and pedals.  The stand has a great
>   feature: it lets one person move the CS-80 by himself.  Since it locks
>   to the keyboard, you can pretty easily (and I'm not very big) roll the
>   unit onto its casters and then move it, and then lift it back up onto
>   the stand.  This is really helpful if there's no one around to help lift
>   it. However, it won't help when you get to a flight of stairs :^)
>
>   Music Rest:  I could never find one of these!  However, I got the
>   outline of one and tried to make one out of clear plexiglass.  Well,
>   cutting plexiglass is harder than I thought, so it doesn't look that
>   hot, but it's ok, and it works, so it's yours, free with purchase...
>
>   Misc:
>   It's got the original Yamaha expression pedal, which can control volume
>   or a wah-wah effect.  I've got a generic foot switch, which can control
>   sustain and/or portamento.
>
>   I'm also including a nice, double-sided printout of the owner's manual,
>   from the Yamaha site.  I'll also give you a CDROM with all the pictures
>   I've taken of the keyboard and every bit of info I've found on the
>   Internet, including schematics, calibration procedures, theory of
>   operations, and more.
>
>   Sale info:
>   I wanted to offer this to group members first (sorry if some people, who
>   are on multiple synth group/mailing lists, get duplicate copies of
>   this).  I'll keep it open to offers until after New Year's Day.  If I
>   don't have a buyer by then, I'll put it on eBay.  Bottom line: CS-80
>   that is better than A+ electronically and about a B/B+ cosmetically.
>   Comes with case/cover, casters, original stand, original expression
>   pedal, generic sustain/portamento pedal, music rest, and re-print of
>   owner's manual.
>
>   If you want one that looks and works better than new, please see the
>   amazing work that Kent Spong does for RL Music (see
>   http://www.rlmusic.co.uk/mals_site/sale_stock_01.html - near bottom of
>   page), but it's gonna cost you about three times what I'm asking.  I'd
>   buy one if I had the money!  Speaking of which, I'm looking for offers
>   starting at $3700.  I'd prefer, and give priority to, local (Southern

>   and drive it away.  As an added incentive, I'll even give it a free
>   tuning (if it ever needs it) after a few months, either at my place, or
>   yours, if reasonably close by.
