The McIntosh 1700 is a hybrid receiver. It has a solid state preamp and amp sections but a tube tuner section. Made from 1967 until 1973 it retailed for $599.00. It is rated at 40 watts per channel in to 8 ohms. The retro futuristic design of the knobs is a distinct feature of the McIntosh which went by the wayside during the 70’s when the clean Tech look came in to vogue.
While McIntosh was known for its build quality and reliability there are a few idiosyncrasies related to these units. The power switch was integrated into the volume knob. Many of these switches have long since failed. Replacement parts are not available so many owner’s bypass the switch and use an external switch such as a power strip to turn the unit on or off.

- D’Arsonval tuning meter for accurate center of channel tuning
- Muting; IF injected circuit with at least 50db quieting between stations
- Nuvistor RF amplifier, Nuvistor mixer
- Four states of IF amplification, with AGC used to insure that limiting occurs only in the limiter stages
- Two limiter stages used for exceptional capture ratio and smooth muting operation
- Multiplex filter and SCA filter, to suppress 19KC and 38KC signal components at least 40db below program and to suppress 67KC SCA by 60db for superior, whistle free tape recording
