but i have to be honest. i found the forum when i googled for polymoog info, since i want to sell one.
anyway, that's how i came here, but maybe it's the start of something nice.

thank you.
and yes. it is a shame.
about 5 years ago i got my first polymoog synth, from germany. i had driven 3 hrs to find it wasn't all together well, but still, i took it home. in the months following i was lucky enough to find another polymoog synth, more dead than alive, but with technical manual and schematics, and a keyboard, for parts. the keyboard was really nice and i loved it, although some chips of the pulse waveform had gone bad and i had disconnected that side of the dividerboard (does this make sense?) to use it as a sawtooth only preset machine. the vox humana still sounded great.
not having any electronical skills or experience, i started reading the schematics and trid to figure out how the signal went from keystroke to audio output. i made exact notes of what i found was wrong in the polymoog synth. after a few weeks of exchanging parts between the two i had one polymoog in good working order, sort of perfect really. the keyboard i used and loved, as it was. and i had a heap of trash (the 2nd polymoog synth.) i remmber, by the way, that on the front panel one of the synths (the early one) was called polymoog keyboard (you know, above the preset buttons).
but then... after a while things went bad anyway, philosophically, i would like to say, that although the moog sound is very much lively and alive, the polymoog reminds us of the fact we're talking about dead gear here, really. and slowly disintegrating too.
it reached a point where my limited skills no longer were enought to do the job and i find that very, very frustrating!
anyway, i sold one synth as-is, with mentioning of the problems, the good parts of the other synth and keyboard. 2 cabinets (well, you know) ended up with the garbage.
i promised myself never to get another polymoog. ever again.
but then i ran into one that was in almost perfect shape and i couldn't resist. i guess it was much better calibrated than the ones i had before, because even the presets sounded good, like the instruments they were named after. i was so happy there, for a while. but now thepulse has gone on some of the keys and there's not much i can do (i haven't taken up any electronics study since the first polymoog experience!)
so, should i haul it over to a repair guy, wait for ages, get it back and play it, in constant fear of something else breaking down. or should i sell and enjoy for instance the sonic6, which i love too, for it's x/y chromosome sequencing and modulation.
you see, that's why i want to sell.
by the way, since the polymoog is so big to ship, i would limit the area very much by selling it in one piece, so i'm considering selling it in parts to recuperate as much of my money as possible.
i'd like to keep it fair though. so, any suggestions on how to best break down the polymoog and price levels would be very welcome. i have had 2 offers so far for the legs and stuff (100 euro and 180 us dollar), there's the manual, and supports for the legs too.
thanks again for the welcome, and hopefully for some advice too.

ok, so i have to admit. it's still fun digging in to it. well sort of...
i opened the case and saw the plenty of electronics and wiring i remembered. i remember how the white wired plugs to the dividerboard referred to 1 waveform and the brown to the other, and, calculating, how all chips connected to 6 keys.
trial and error has learnt that the far left row of divider chips is not working, at least, these 3 connectors, when disconnected don't make any change in poly's performance.
i seem to remember these chips were connected in series, in some way, so i am now assuming one of these 3 chips has gone bad, affecting the first row's performance. doe any of you experts know, how they are connected and from what i have posted, canit be determined which one has gone bad? (the 2 top chips on the far left are soldered in the board, but the bottom one has been replaced before and is gently seated.
any help or suggestions will be much appreciated. thanks.

i guess it's about time to move my posts to another section....
i have switched the one bad chip which was mounted in a seat with another one like that, further on up the board and found that many, many keys were effected then. so i guess i was right about the serial connection and it seems that luckily the bad chip can easily be replaced without soldering.
now, te big question, can anyone help me to such a chip?!
thankx.
