Hello friends, For my 10 GHz TWT type W3MC12D, manufactured by STC, I’m looking for: the data sheet or instruction manual of the TWT, including the pinout of its connector and the voltage ratings of each pin, and the DC power supply, type PW35A (as indicated in a STC catalogue of the eighties) I know very well that the 2nd item is harder, therefore the 1st one is the most important, for the scopes of checking the correct operation of the power supply or building a power supply… Every help is very appreciated! I wish you a better 2022, full of satisfactions and serenity.
