Thanks, John. You are right, I misread the specification of frequency adjustment. By varying the EXT. C-FIELD VOLTAGE I can now change the frequency from 9.999.999,960 to 10.000.000,023. Unfortunately, there is no change when I move the pot from one extreme to the other, so the question about maintenance is still valid.
If there is no hope of maintenance documentation, a precision voltage regulator and a 10 turn pot will allow calibration. The unit has both the lamp and crystal voltages well in the mid range, so I expect a long life. -- ------------------------------------ Geraldo Lino de Campos [EMAIL PROTECTED] _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
