Hi everyone, I used my Otari MTR-15 for the first time in a while earlier this week and have found that one channel is not erasing in Record mode. I have narrowed down the issue to one of the Bias Control cards (PB-4PV), and although I believe the issue could be a bad relay on that card, I need a schematic to assess exactly which component(s) have failed - hopefully it's not one of the Otari proprietary ICs on the card.
So my ask of the group is this - does anyone own schematics for the MTR15? The service manual available does not contain them. I saw a thread from about 4 years ago on the Tape Project site where folks were looking for the same thing and that post died off, though Ki indicated he may have the schematics, so I wanted to revive the thread on more active Forums, not only for my own selfish purposes, but also for others in the community who own these wonderful, if complex machines.
I would be happy to foot the bill for high-quality duplication and digitization of these documents as I am currently aware of no one who has hardcopies of the schematics.
Also - do any owners have extender cards they'd be willing to sell? If not, I can have extender cards fabricated as I've located the male and female card connector parts still in stock at multiple vendors online, I would just prefer not to do so if it's not necessary.

Note - this has been cross-posted in another forum for best coverage and will report back progress in both locations. If I obtain the schematics, I will be happy to share.
