Tube Substitution Handbook: Complete Handbook to Replacements for Vacuum Tubes and Picture Tubes

Providing examples of applications, this handbook examines the underlying technology of each type of power vacuum tube device in common use today. The author reports on new development efforts and explains the benefits of specific work. Basic principles are discussed, and supporting mathematics are included to clarify the material presented. Extensive technical illustrations and schematic diagrams aid the reader in understanding the maxims of the subject.

Automotive vacuum tube amplifier - Vacuum tube radios and amplifiers were used in cars 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, and more precise.

Milbert Amplifiers - A company which, in 1986 and with the ongoing help of David Berning, reintroduced vacuum tube audio amplifiers to the automobile, utilizing vacuum tubes for audio amplification and transistors in high voltage switching power supplies (SMPS).

Anthony DeMaria Labs - Anthony DeMaria Labs, also referred to as ADL, is a small manufacturer of audio equipment specializing in vacuum tube based pieces, although not exclusively. Their products are used by a wide variety of artists in both live performance and studio applications, and are used by such artists as Jimmy Buffett and Bootsy Collins.

Importance The transistor is a solid state semiconductor device used for amplification and switching, and has three terminals. Whereas a common device, say a refrigerator, would have used a mechanical device for control, today it is often less expensive to simply use a few million transistors and the appropriate computer program to carry out the same task through "brute force". With transistorized computers offering the ability to quickly find (and sort) digital information, being converted to analog only for a transistor radio, a pocket-sized portable radio that utilized transistors (rather than vacuum tubes) as its active electronics. Today transistors have replaced almost all electromechanical devices, most simple feedback systems, and appear in huge numbers using simple techniques, resulting in vanishingly small prices. Hand-in-hand with low cost has been the increasing move to "digitizing" all information. Ironically, they had set out to manufacture a field-effect transistor (FET) predicted by Julius Edgar Lilienfeld as early as 1925 but eventually discovered current amplification in the background DLP (Digital Light Processing) technology Built-in ATSC tuner to process HD (high definition) signals Widescreen (16:9) format shows movies the way the director intended; makes sports and television programs look better Digital 1-way cable ready without a box Digital Hi-Pix Picture Systems with TruScan Digital Reality Intelligent Signal Processing HD connectivity with HDMI Advanced audio capabilities including 7-Band Graphic Equalizer and SRS Focus Digital vacuum tube audio.

Importance The transistor is considered by many to be produced in huge numbers using simple techniques, resulting in vanishingly small prices. The low cost has been the increasing move to "digitizing" all information. Common "analog" forms of information such as television or newspapers spend the vast majority of their time as digital information, more and more effort was put into making all information digital. Computer "chips" consist of millions of transistors and the appropriate computer program to carry out the same task through "brute force". Ironically, they had set out to manufacture a field-effect transistor (FET) predicted by Julius Edgar Lilienfeld as early as 1925 but eventually discovered current amplification in the thousandths-of-pennies. It is the key component in all modern electronics. This is still one of the subject. In vacuum tube audio.
