Low distortion is a requirement tor high performance
in a preamplifier. A typical wave form analysis of the
C 26 at 2,5 volts output is a 99 95% perfect reproduction of the input wave, 20 Hz through 20,000 Hz!
RELIABILITY
Endless hours are invented by our engineers carefully
and thoroughly testing and retesting individual component ports. These hours ore required to provide
you with the highest degree of reliability that modern
design and manufacturing can produce. As an example: The front panel is constructed of materials that
are nearly indestructible. The combination of anodized aluminum and glass are impervious to attacks
by acids and oils. The subtle beauty of the C 26 will
remain unblemished year, after year, after year. This
