All About Raytheon NOS Tubes
Raytheon NOS tubes provide a replacement part for a variety of classic musical devices requiring vacuum tubes. Guitar amplifiers provide the most common use of tubes. Replacement Raytheon vintage tubes and other kinds of NOS tubes can be found from the 1950s, 1960s, and 1970s.
What does the abbreviation NOS stand for?The acronym NOS stands for "new old stock," "new on the shelf" and "new off the shelf." NOS refers to original parts for classic equipment not yet sold at retail. It means the product was manufactured previously but not available for sale at that time. No longer in production, the supply of these items extends only to what was warehoused and not offered for sale.
For what purpose would you use a Raytheon tube?Classic televisions, radios, guitar amplifiers and motor vehicles all use vacuum tubes to power various systems. In TVs, they created the "glow" from the back of the unit that brought light to the screen. If your set's tube blew out, you had no picture even if it was plugged into the wall outlet. Replace the part and the set worked again. For bass and guitar amps, these tubes provide power and tone.
How does this product affect the tone of an amp?Use this product to alter your guitar tone. In an analog amp, this part powers amplification, but also causes distortion to the sound. When an amp runs clean, it provides very minor distortion. Changing the model of vacuum tube used alters the tone. When you strike a string on an electric guitar, it sends a signal to the pickup which transmits it to the amplifier. Inside a solid state or digital amp, it hits a circuit board that generates a clipped, square wave amplified sound but, in an analog amp, it hits the tube which generates a warm, round wave with harmonics.
What musical genres might use this type of amplification to influence the sound?According to Premier guitar, about 99% of professional guitarists continue to use this amplification method during recording and touring. The tones achieved by their use continue to form the "cornerstone tones" of the blues, country and rock genres.
What kinds of parts are inside the glass tube?The glass bottle that comprises the outer portion of this part contains four pieces inside a vacuum seal:
- Anode (also called a plate)
- Cathode
- Filament (also called a heater)
- Grid or grids
When this product contains an anode, cathode, and grid it is known as a triode. However, when it also contains a screen grid and suppressor grid, it is known as a pentode.
