12 KW CCS ON 160-15M....USING THE 3CX-6000A7..... PART 23
Here, the 7.0 vac @ 80 amp CCS? ?fil xfmr and the mating? 4 amp,? 240 vac variac is installed.? ?Along with the pair of 100 amp? CCS rated....'supercon connectors'.? ?4 ga wire? from supercon connectors? over to RF deck...where another pair of 100 amp connectors will be installed.? ?The supercon 100 amp connectors use? 5/16" studs on the back end. (The larger 250 amp version uses? 1/2"? studs? They also come in a 50 amp version, using 1/4-28 studs......and also a 25 amp version, using 10-32 studs).? The power supply is progressing slowly due to time constraints.? Fil voltage will be measured at the cathode terminals....via a small RF choke in each leg.? On new / rebuilt tubes, it's run at rated V? for the 1st 200 hrs. Emission increases during the 1st 200 hrs, then levels off.? ?After 200 hrs, the fil V is reduced by 10 %.... like down to 6.3 vac.
