"Oberheim Service Notes from 1980's in Oberheim 3 Ring Binder
These documents comprise an official Oberheim issued compilation of Authorized Service Notes.

These are NOT Oberheim Technical Service Manuals.

They are Engineering Change Orders (ECO's) which are mostly circuit updates.

Each ECO has been implemented over time to improve the performance of a particular Oberheim Model.

They have been grouped to include all the changes to a particular model.

The OB-Xa Bulletins for example are grouped into the 100 series; The Expander is the 600 Series.

One would still refer to the actual Oberheim Service Manuals to actually perform these updates.

View this binder as an Addendum to each of the Service Manual models on the list.

The Bulletins cover:

Model_____ECO-Nmbr

OB-Xa_____100-145

DSX_______201-217

DMX_______301-338

There are no OB-Sx Service Notes.

There may be a couple of Service Notes missing. Either they went missing or were never there.

I used to be an Authorized Oberheim Service Center, but Oberheim went out of business

and resurrected as ECC Oberheim, then I believe went out a 2nd Time.

I lost on that deal - due to Unreimbursed Warranty Claims.

The package weighs over 6 LBS. which is charged as 7 LBS per USPS."
