OK, here goes, 1958 Janssen Model 07 Piano-Organ Schematic Needed

I should probably seek counseling for even attempting to get this thing working, but I feel I must give it a shot 8)
Web search turned up nothing but if anyone has one it would surely be on this forum 8)

Thanks!

I know of these instruments, but, alas, don't have a schematic. May I caution you, though? On the Piano Technicians Guild List, one of the RPT (professional) members encountered one. She said that after she tuned the piano, the owner turned the unit, with its numerous vacuum tubes, on and played a while. She said that within 30 minutes, the heat from the electronic unit, which was of course inside the piano's case, "trashed my tuning".
Something to think about, no?.

You bring up an excellent point, thanks! The thing has *70* tubes 8) I figure this system has a value *way* less than zero so I'm going to try tuning myself. I guess if (big if) I get the organ subsystem working I'd best tune it hot!
