<< Hello All,
 
     I have incorporated my properly ballasted 5 Kva pig.  I got one of
 Richard Hulls tapes on magnifiers.  I have be building magnifiers for a
 couple of years with good luck.  Now the old system used a water pipe as
 ground, 10 kv,300ma input, and ran like a champ with an intense 6'
 streamers for 30 minutes with out  any problems.
     With a 14.4 Kv input and an equa-drive set up I can't get hardly
 anything out of it but an occasional thin 6 inch streamer.  So I went back
 to my old tank configuration with one cap.  This I did because I know it
 worked and where the tuning was.  Guess what; it still had the same poor
 preference.
     One thing is I have three grounding rods separated  8 ft apart and
 soldered together.  A good solid rf ground.  Maybe this is the problem, I
 don't know.  I have added a quench gap in series with the rotory,  could
 the problem lye here? 
     I suspected that with the higher power the quench is a lot harder to
 get,  but that is why I put in the quench gap.  It has eight pipes ( 1.75"
 dia x 2"long) and has a plenum with a 150 cfm blower forcing air through
 the 1/8" gaps.
     Anyone has a clue as to the short coming of my "up-grade".  Any help is
 as always greatly appreciated.  By the way, the TCBOR tapes are worth the
 money,  especially those of new experience to TC's.
 
 Thanks,

Dwight,

Your grounding system sounds just like mine.  My three rods are interconnected
with 3.0" wide copper flashing.  I also use a 5kva tansformer and did use a
static gap in series with the rotary - but took it out at the advice of Bill
Wysock.  Did you use the rotary with the 300 ma 10 kv supply?  I would guess
that you would have to.  My suggestion would be to fire the system with the
old power supply and see what happens.  If that doesn't work, keep restoring
the system to the original configuration one step at a time until you find the
problem.
