In addition to the data I have scanned and posted, if you're looking for data on a particular tube you should visit TSDL on Duncanamps website, or Frank's tube data.Another spot to look, which is especially useful if you're looking for replacement types and tubes with similar bases or characteristics, is the NJ7P tube database. I am working on posting the RCA HB-3 Tube Handbook on line on this ...

MOSFETs can be used to replace any vacuum tube in a typical receiver except in the audio output and power supply. In addition to the circuits already discussed, recent editions of The Radio Amateur's Handbook contain other MOS- FET circuits which may be used in a conversion. The use of transistor sockets allows experi-

3/20/2012 · Everyone relied on the RCA Vacuum Tube Handbook as the bible for specs on the parts. Wouldn’t it be cool to find an old copy? And wouldn’t that be utterly pointless? That thought morphed to memories of the other indispensable tome of the time: The GE Transistor Manual. Not too many clicks later and one was on its way here.
The audio transistor used in a linear amplifier’s output stage typically is a fairly high-voltage device. ... The vacuum tube will conduct a lot of anode (or drain) current for a near zero ...
A good choice for phase inverters, reverb drivers, and general preamp use. This tube offers low noise, low microphonics, and warm smooth tones at a great price. Like all JJ tubes, it has a rugged construction that doesn’t compromise the sound of your amp. The JJ 12AT7 is a solid replacement for any 12AT7, ECC81, or 6201 tube.

The invention of the vacuum tube diode by J. Ambrose Fleming in 1904 and the triode vacuum tube amplifier by Lee De Forest in 1906 launched the electronics industry as we know it. The De Forest invention was pivotal. It marked the transition of the vacuum tube from a passive to an active device.
AND THE TRANSISTOR MUSEUM™ This book is the first of a series of History of Transistors publications developed by the Transistor Museum™. The History of Transistors Volume 1 documents The First Germanium Hobbyist Transistors, a subject that should be of great interest to the modern-day experimenter, engineer, historian, researcher and hobbyist.
The Radio Amateur's Handbook, 1964, pp. 133-139 This ham band 80 -10 five tube (6BA6, 6U8A), two transistor receiver includes a 100-kHz calibrator. An Inexpensive 75-Watt Transmitter The Radio Amateur's Handbook, 1964, pp. 172-175 This crystal controlled transmitter for 80-, 40-, 20-, 15-, and 10-meters uses a 12BY7 and a 1625.
How Vacuum Tubes Work by Eric Barbour - [Inside a Tube] - [Why are Tubes Still Used] - [Using Tubes] The BASICS. Back in 1904, British scientist John Ambrose Fleming first showed his device to convert an alternating current signal into direct current.
— in a vacuum tube, metallic wire heated by electric current; may serve also as the cathode in some tubes. gate — part of an electronic device such as a field-effect transistor that controls the passage of current. in a vacuum tube an electrode that grid controls current flow. hand key — a device used for sending Morse code.
