I have a copy of the operation manual but I still need the service manual. Any help would be greatly appreciated.

I really underestimated how complicated this thing is compared to my R500. I can't even seem to get it play a tape and show levels.

Make sure the clock is set to internal and the correct Sampling Freq


Unfortunately I only have a couple of different copies of the owners manual

Also I am pretty sure the CUE button needs to be active in order to play a tape

Thanks for all the suggestions but I think there is more going on than user error. I have yet to see the servo lock (green light) illuminate and I think that may be the problem.

My 7040 came with a bad loading mech (someone fished a tape out and damaged the gears), bad pinch roller, and dead capstan motor - I replaced the loading mech and capstan motor from a used donor Sony SDT-7000 DDS drive.


For the pinch roller most any Sony DDS/DAT pinch roller will work - you can buy a new one from Paul at prodigital for about $30 shipped.   Full Compass used to sell these as well.


The 7040 has well documented error codes as well - that can help you pinpoint the issue.  Open the top and watch the tape load as well.
