Looking for a lead on a JVC BR-D51U D-9/SVHS svc manual
 

More or less as in the title... I'm looking for a lead on a service manual for the JVC BR-D51U playback deck. If you're curious, this was a Digital-S (later renamed D9) deck that happened to play back SVHS. I've been searching high and low for a service manual so far to no avail. I'm hoping someone here has better Google-Fu than I do.

More background - I've finally gotten the deck working after about a year of on-and-off work without a service manual but I want to dive into calibration.
