[R-390] R-390 : L903 in the Calibrator Module

[Jacques Fortin]

Hi John,

Yes... 0.5µH for an oscillator running at 1MHz makes no sense (only 3.14
ohms of XL).
Have you also changed the value of C 905  (from 150 to 200 pF) ??
I also read yesterday that the V901 and 902 have to be 5814As, maybe to
better resist cathode poisoning (filaments on but no plate current most of
the time).
Is your calibrator working OK with L903 at 0.5mH ??
