Hello,

Need info. on an E. F. Johnson, split stator variable capacitor.  The 
Johnson label is damaged and all the information that can be obtained 
from it is: 0.125" spacing, Model No. 1X3-906 (the "X" looks like a 5 
and the "9" is not that clear either).

The capacitance of the sections, as measured with an Autek Analyzer 
at 3.5 MHz, is 70 -20 pF and 140 - 30 pF.  The number of plates per 
section is 8 rotor and 7 stator, and 4 rotor and 3 stator.

Need information on what voltage this capacitor can support and are 
the measured capacitance values correct?

         73,
         Mike, K4GMH
