Hi there, you should check and confirm that the PSU is working properly, especially the 5V line. I am not a synth tech guru, but the symptoms that you describe remind me of a dead cpu board. By "dead", I mean that the unit does not initialize at startup and that could be caused by a defective eprom,...

Are you looking for the prophet 5 rev2 schematics ?

Please have in mind that if you use Wd40 it will take all the rubber coating off, it will not just remove the stickiness.
You better test it on one knob and see the results.
Maybe it would be easier to buy a new set of knobs?
good luck

Sorry for resurrecting this old thread, but I am having exactly the same problem as Z. I bought new lubricated P-R bushings from vintage vibe, cleaned and aligned everything properly but the keys feel sticky ! My keys are all plastic , there is nothing metal to widen. Z, how did you solve this probl...

The TC Electronics and Klark & Tekniks logos printed on the synth are so lame.
How come it doesnt say MIDAS too ?

Dont worry ,you are not alone, I have noticed that the same thing happens on Alesis Ion knobs and on some waldorfs. It even happens on expensive JBL studio monitors and on car plastics. It is the rubber surface that deteriorates so quickly, I thought that it was a problem related to sunlight. Wd40 c...

I doubt that the files are corrupt, maybe you should try winrar. I am having issues when loading disks on my S-50, some of them prompt "Disk Ver. Error". For example this volume "RSB-504 10 ANARCHY TIME!", gives the same error . I have used both images from llama and sgroup but the same happens, tha...

thanks for replying Robin, I have already checked there but they have only the 8 RSP volumes.
I am looking for the 5 disks that came with the unit, they are coded Z6‑S050‑01 through Z6‑S050‑05.
thanks

Sorry for reviving this old thread, but I need the library for my S-50.
D-Collector can you please re upload it ?
I have downloaded the library from lamamusic.com but I am having a few issues.
thanks

Ha ! It is Alex Reece in the Goldie era !
So what synth did he use for the pulp fiction bass ?

Hi guys, I am repairing a dead S-50 ( Does not boot up, stuck with leds on) and I have traced the problem down to the eproms that hold the firmware (IC64,IC65) I have noticed that Syntaur sells the v2.04 firmware, it should be the latest. Syntaur has no eproms for the S-50, only for the S-10 :( Can ...

Do other cards work as expected? You 'd better confirm that the switches are working right, dirty switches can make intermittent contact. You can try cleaning them with a few drops of rubbing alcohol or contacts spray. Other than that I cant think of any other failure except the eproms. Maybe it cou...

Rumors say its either a Waldorf microwave or a Korg 01/W

A couple a years ago, I repaired a Nord lead 3 that was connected to 230V instead of 110V and was accompanied by a loud boom. On inspection, the fuse was not blown, the problem was on the transformer which had one contact lifted off the pcb. I suspected a transformer failure, but resoldering the con...
