cutoff for the horn assembly are fed to the
driver, excessive current may be drawn the
by driver. For protection of driver, amplifier,
and transformer (if driver with built-in
transformer is used), capacitor(s) in series
with driver, or transformer primary are
recommended.
For drivers without transformers:
or two 150 V dc electrolytics of two times
required value in series, back to back, for
70-volt lines.
