Arp Odyssey Rev 3 service info

Arp Odyssey Rev 3 service info

2009-06-08 by stadmar500

Hello, I've recently acquired a non-functional rev 3 odyssey, and I've been looking for service information for it, but I haven't found much (mostly just some neglected websites with dead links).  I believe this unit might have a power supply issue since it does not power up when it is turned on; the unit has been well taken care of (aside from some dirty sliders) and appears to be in great condition aside from the fact that it won't power up.

I'm interested to see if anyone knows of any working links to a rev 3 service manual or any other advice to troubleshooting this problem.

Thanks, I appreciate any help!

Damon

Hello,

I'll send you a link to a service manual in another mail.

I find Odysseys quite easy to service.

First thing you should do is to remove all the power connectors from the
three boards and see if the power supply puts out the required +15/-15
volts then. If it doesn't the supply is the problem. If the +15/-15 volts
are there probably one of the boards has faulty tantalum caps.

Hi, thanks for the info!  I would definitely like to see a link to the service manual!

I'm glad to hear that odysseys are fairly simple to service; they look so simple and clearly laid out inside!  I just want to make sure I'm testing the right locations and not shorting anything out.

Thanks again for your help, I appreciate it!


Damon

Hi Damon,
If you have the power supply ok and no tantalum caps fauty, don´t forget to check the pots because they usually make the Odys dead in some cases.
Because the age of these instruments, the resistance of the slide pots comes to get altered and it causes a lot of different problems.
Thanks and good luck!

Please check your mail (and possibly your spam folder), I sent the link
directly to your yahoo address a couple of hours ago.
