Hi John -

The Murch units were of excellent quality and could take just about all you
wanted to put into it.

The older 2000A did have some problems with the turns-counter arrangement
and if you forced the roller inductor, you could make it skip over the end
stops.  The early models DID NOT have a balun.

I owned an early version of the unit, but sold it to buy a 2000B which
covers 160-10 meter.  The early versions did cover 160 meters.  Been using
it for years and have absolulte no complaints.

Now, as far as a manual.  The units did not come with a manual as you would
picture a manual.  The little instructions that came with it, told you where
to place the input and output capacitors for a start(Input Cap at 1.5 and
Output at 2.5).  It then told you to move the output capacitor ccw until you
saw a dip in the reflected power.

Next the Input Capacitor was to be rotated clockwise until you saw a dip in
the reflected power and you were to move just past that point.

Now move the output cap CCW until you see another dip.

Continue this process until you note little or no change...Reflected power
should be at or near Zero.

All this is done under low power...Touch-up can be done under "full" power.

Great unit...You did not go wrong.
