Performance Limits 11 - McIntosh MR 7083 Owner's Manual

PERFORMANCE GUARANTEE
Performance Limits are the maximum deviation
from perfection permitted for a Mclntosh instrument.
We promise you that your MR 7083 must be capable
of performance at or exceeding these limits or you
get your money back. Mclntosh is the only manufac-
turer that makes this guarantee.
