Here is a prime example of
how small standard
electrolytics have become. On
the prior page you probably
notice something different
between the pictures but
could not quite put your
finger on it.
A large capacitor was laid on
its side to avoid interference
with the wire wrap posts. This
cap is soldered in parallel
with a diode (a "reverse
recovery" current is caused
by sudden voltage changes to
the diode. This sharp current
edge causes high frequency
noise, which is trapped by this
capcitor). It lies over the top
of three resistors.
The replacement cap is less
than one quarter of the size.
It now stands upright!!! Notice
the two capacitors to the right
are also smaller. Note the
circuit markings (circles)
