McIntosh tube type tuner/preamp. Serviced,refurbished,updated, detailed by Tri-City Electronics. List of parts and service performed available. Includes McIntosh wood cabinet. Beautiful in appearance and operation.Best MX-110 I have ever seen. The MX110 combines in one unit an extremely low-distortion preamplifier with a highly sensitive FM multiplex stereo tuner. Every desirable feature of a tuner and a preamplifier is included in this design. Interstation noise suppression, tuning indicator, FM multiplex indicator, individual channel bass controls, individual channel treble controls, electronic phase switch have all been engineered into the MX110. The INPUT SELECTOR gives you a choice of six different program sources. The MODE SELECTOR is a newly developed control which makes it very easy to balance a stereo system. It is designed to add left to right for monophonic operation, to control the left to right stereo perspective or to compare the left and right channels of a stereo program. The loudness of the phono channels and the auxiliary channel may be balanced to the tuner loudness. These adjusting controls are located on the top of the MX110 behind the front panel. By releasing the PANLOC buttons on the front panel, you can slide the MX110 out of its mounting until the second latch engages. The top mounted LEVEL set controls are now available. The McIntosh designed PANLOC system is the first professional installation technique to be used on stereo instruments. The PANLOC system gives you absolute ease of installation, operation, and maintenance. The McIntosh MX110 is a beautifully engineered control center for the finest stereo sound systems. The extreme care in manufacturing, in layout design and in thermal engineering promises the usual Mclntosh extra values of reliability, performance, and long life.
