Solid State Preamplifier

Performance is important to your listening expectations. With a Mclntosh you are assured of highest performance because McIntosh guarantees performance. Your C 26 must be capable at meeting its adv e r t i s e d p e r f o r m a n c e limits or your purchase price will be refunded. Mclntosh promises performance and delivers performance. 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 attention to detail increases the value of a Mclntosh at trade in time. And because of the testing program, Mclntosh promises you complete freedom from service costs for the first THREE YEARS that you own your C 26.

You get complete protection from all service coat lor three full years. Only Mclntosh offers a tree THREE YEAR SERVICE CONTRACT. You can't pay us to service your C 26 for the first three years you own it. Both parts and labor are included in the service contract. You are assured of highest performance because every unit is individually tested using internationally recognized test procedures. You are assured of greatest reliability because every component part is carefully tested and evaluated before it is designed in a Mclntosh. The Mclntosh C26 in the finest expression of PERFORMANCE RELIABILITY - FLEXIBILITY BEAUTY.
