Wersi Comet

Beitrag von Fonsspons »

Hi you all,
got my hands on a free wersi comet! What a nice (but heavy!) machine! A lot works, but allso some things don't. So I tried to open it. But I only managed to open the top lid. I'm unable to find out how to open the first and second keysections. Anybody got tips?
Thank you!
(Oh, and anything manual and/or schematics would be much appreciated!)
Jo

As I remember ther are two long screws from underside which hold the upper manual.
The lower manual must be fixed with two screws just under the front side.
All that screws You find at the wooden side panels

The main thing when anything doesn´t run in this organ are the plugged in flatcables direct at the
PCBs in Rack.
The black plastic connector is broken at small sides so that there is no contact any longer

Second mistake in those Organs is the power supply card PS 10.
Mostly this card is overheated and no chance to repair !!!
You must then rebuild this powersupply which generates 4 different voltages separated with greater
cooling plates for the transistors

I send the manual for the Wersi Comet (in german documentation).

Repair for the power supply PS10 may be possible - the PWN power supply Controller can be buyed by eBay (https://www.ebay.de/itm/162867196961)

Thanks for the manual!
At first sight, the Comet works quite ok. It took me a while to figure out it's function. It's not so intuitive as the DX500. Most of the effects seem to work but still have to look in to that.
The piano section has an intermitting problem with the "piano lang" button. After this button is activated any generated piano sound is endlessly repeated.
The wersimatic CX2 seems to work, I can see that via the programmer board. When start is pushed you can see a led pattern playing. Alas, no sound is produced.
Then on the left what is the magicfingers (?) I don't know if this works, maybe mostly because I have no clue what it's supposed to do nor how to work with it.

The only thing from Magic fingers I have is the Data Cassette.
But no guarantee if data still OK
Perhaps - but I´m not really shure and I must search - the AOC PCB too

Maybe the user manual for the "Magic Fingers" may help you...
