10 KW CCS ON 6M...USING THE 3CX-6000A7... PART 22

Here, the pair of 7.5 vac @ 50 amp CCS fil xfmrs are wired in parallel, and
installed on the chassis of the HV supply.
They will be used to power the 7.0 vac @ 78 amp fil of the 3CX-6000A7
triode.  Both 240 vac primary's are wired in parallel...and also the 7.5
vac secondary's.  Scott has plenty of spare 7.5 vac @ 50 amp fil xfmrs, so
it was decided to use 2 of em for this application.  Output of the small
0-280 vac @ 4 amp variac is wired to the paralleled primary's of fil xfmrs.
HV rectifier + bleeder resistor assy to be installed next.

The new 3CX-6000A7  arrived from Penta, and is unboxed, to show how they
pack them for shipping.
