Ampex 750

The Ampex 750 is a solid-state quarter-track stereo reel-to-reel tape deck produced around 1969 to 1972, designed for consumer markets with advanced features for its time. It supports 1/4-inch tape on 7-inch reels and offers three tape speeds: 7½, 3¾, and 1⅞ ips, allowing flexibility for various recording needs and durations.

Technically, the deck features two long-life Permalloy heads configured for stereo operation, and employs a dual-capstan drive mechanism to improve tape stability and reduce wow and flutter, which is rated around 0.15% at 7½ ips. The device includes an automatic shut-off function and automatic tape lifters to protect tape and heads during fast winding.

User interface controls consist of push-buttons for transport functions positioned on the deck's left side, and two VU meters for accurate record level monitoring. A three-digit position indicator aids in tape navigation. The deck has extensive input/output options suitable for connecting various audio sources and amplifiers.

Its frequency response spans 15 Hz to 15 kHz at 7½ ips, delivering reasonably wide audio range for consumer stereo playback and recording. The unit measures about 13¾ x 16 x 8 inches and weighs around 32 pounds. Originally priced moderately at around $199, it was marketed as offering "famous Ampex quality at a moderate price."

In summary, the Ampex 750 stands out as a reliable, feature-rich consumer reel-to-reel tape recorder with solid-state electronics, multi-speed capability, dual-capstan tape transport, and user-friendly controls, suitable for home audio enthusiasts aiming for quality stereo tape recording and playback in the late 1960s and early 1970s.
