I attempting a diagnostice restart of a JSM 840.  When I emailed  JOEL sales engineer to attempt to purchase technical infomation I got this reply " ..sorry nothing. Engineers came here and learned on a training instrument or working with another engineer in the field"  I assumed around a campfire with scary stories of the quantum world - LOL.  The JOEL web site has online websales however I would need the parts number for the documentation. Does anyone have the part number for the technical info  Where can I find help? Also I have a degrees in physics and electrical engineering and know the difficulties involved I just need the information.

We have a service manual for a 840F, perhaps a 840 if you are still looking. Also parts.
