E2000 buffer board

[LDM]

I've had my E2000 for a while and been wanting to get the sound working on it.  Apparently mine has the sound board installed but is missing the buffer board that is needed to make the sounds play while the machine is in operation.  I know the sound board works as the test works fine for it and it also makes sounds on startup.  I don't see much on the buffer board and can't seem to find one available anywhere online.  Does anyone happen to have one or know where I can get one?  K Lar is usually where I have been getting my parts for my 2 Bally machines but he doesn't seem to have this part either unfortunately.
