Automotive vacuum tube amplifier
- Automotive vacuum tube amplifier
Vacuum tube radios and amplifiers were used in automobiles until being displaced by transistorized radios. This shift occurred for the same reasons as in almost all other electronic devices: transistors are smaller, cooler, cheaper, more durable, use less power and are ready to operate much quicker.
Some enthusiasts prefer "tube amps", so a small number of tube car stereos are still made. Manufacturers include Milbert Amplifiers, Blade, Manley, and Sear Sound. Some are "hybrid" designs with transistorized power supplies and a few "token tubes".
