[BC] Are they all this way? (crunchy Compellor)

[lists at loudandclean.com]

      Agreed, I have routinely bypassed this stage as well in my plants,
matter of fact there is a unit with this mod three feet from my right
elbow at this moment (OK, OK, 38 inches), however:
          [1] many folks on this list don't like internal mods,
          [2] the cross-coupled output can drive super long lines
             (current source transistors and a ten-ohm source
              impedance), and
          [3] the load resistor solves the glitch problem, so
I didn't want to suggest this mod to the list-at-large.

      Of course, bullet-point two above raises another issue. . . you
should NOT connect a compellor directly to a transformer input
that "wants" to be driven by a 600-ohm source. . . the transformer
will not perform well with a super-low source impedance.  Insertion
of a 270-ohm resistor in series with each side of each output
(pins 2 and 3) solves the problem.  In this case, the glitch problem
doesn't exist, so THAT resistor is not necessary.
