Made in USA

The Dynaco Stereo 120 is an all silicon transistor basic power amplifier for use with separate preamplifiers such as the Dynaco PAT-4 or PAT-5, or for use with tape recorders or tuners such as the FM-5 or AF-6, which have their own volume controls.

The unit contains two 60 watt amplifiers on one chassis with a common power supply.

Although the Stereo 120 is a solid state device, containing transistors and similar semiconductors, it has been designed to be used under normal conditions without special safety precautions, just as if it were a high grade tube amplifier.

Thus it can be connected to source and speaker components and used with confidence in all conventional arrangements.

There are no circuit breakers, speaker fuses, or other resettable devices to impede the use of the Stereo 120 under any reasonable conditions of use or abuse.

This is achieved by using novel circuits (on which patents are pending) which automatically and instantly protect the amplifier.
