RAYTHEON T-150-4

This Raytheon T-150-4 was manufactured in the USA in 1955/56. It features a smart, snappy design with a beautiful tuning dial that reminds me strongly of a valiant Viking shield. It also features a dashing little cloisonné badge on the left emblazoned with an R and a spinning atomic symbol. The script proudly proclaims ‘Raytheon Transistorized Deluxe’.

These are fairly rare radios and they are especially coveted by collectors with some willing to shell out the big bucks in order to acquire one!

Raytheon was founded in 1922 and began specializing in the production of vacuum tubes and other electronic devices. ‘Raytheon’ is Greek for ‘god of life’. Raytheon chose this name for its modern sound.

In 1940 Raytheon began defense contracting for the British and US Governments manufacturing the top secret Magnetron, a microwave radar tube. By 1944 virtually every US Navy Ship was equipped with a Raytheon Radar.

Raytheon continued defense contracting during the Korean War and in 1956 sold its radio and television divisions to the Admiral Corporation. There is obviously more money to be made in missiles than in pocket transistor radios!

Today Raytheon is the third largest defense contractor in the USA.

This Raytheon features an unusual cabinet design. On the majority of radios the chassis and battery compartment is accessed by removing the back. On this T-150 the chassis is accessed by first removing the tuning dial and the screw beneath it and then lifting the front speaker grill.

The battery compartment is also separated from the main chassis giving this radio an advantage over its competitors in case of caustic battery leakage, a rather common occurrence during this time. The battery compartment uses a unique latch to open and close it.In cabinet design Raytheon were certainly leaders not followers!

Looking inside some of the little blue CK722 transistors are visible. Introduced by Raytheon in early 1953, the CK722 was the first low cost junction transistor available to the general public. It was an instant success!  Countless “build it yourself” articles were published in the popular electronics press and electronics/hobbyist magazines describing how to use the CK722 to build all types of devices such as radios, oscillators, electronic voltmeters, photoelectric alarms and hearing aids.

This T-150 was obviously built to last as it still works well today.
