| X4041 C. EFC. BY/RD3/ML.31.3.27. CONDENSER - 20 & 40/50 CHASSIS - SEC:8130. It is desired to try a condenser having the maximum number of turns possible with the present case, the standard is 28, but we think that 36 might be possible, therefore, would you please put in hand two condensers to D.70936 but having the maximum number of turns possible. The piece number will be D.71345 and if you will advise us how many turns are on we will put it on the drawing. BY/RD. | ||
