I have an older Boss TU120 tuner (maybe 1979) that seems to need
adjustment
repaired, but have been unable to locate a schematic or service manual.

The output frequency at the Monitor jack, appears to be incorrect for the
internal Calibrate settings, and when checked with a reliable counter
(SC3100 AutoTracker readout) the freq is about 432Hz, when I think it
should
be adjustable to over 440Hz.

I was about to ask Roland Support when I saw that they require registered
user identity sign-in/account to be established before asking a question.
