Hi all,

The calibrator module of my R-390 never had any "MOD" applied so L903 was
never assembled in.
Not that it was not working the last time I used it, but...
I am not sure about the L903 value: the MOD list on page 4 of the
TM11-5820-357-35 indicates 0.5mH (500µH)
but the schematic itself indicates 0.5µH (500nH).
Which value is the right one ???
BTW, L903 is not listed in the TM11-5820-357-35-P (the parts list).....
