It has much higher transconductance, and much lower dynamic plate resistance than a 12ax7. If this is a car radio with space charge tubes 12 volt plate voltage. Etc, alldatasheet, datasheet, datasheet search site for electronic components and semiconductors. Look for the section hybrid automobile receivers on page 415. Vacuum tube 1u4, pentode miniature, filamentary, sharpcutoff pentode intended for radio frequency or intermediate frequency amplifier use in batteryoperated receivers. For example, i built the 3v4 bcb receiver from harry zarchys kidhobby book using. The 12bv7, 12by7, 12by7a, and equivalents were a class of mediumlow gain, pentode vacuum tube amplifiers using the noval socket configuration. If so, and you want to run it as designed from the 12 volt car battery or equivalent supply.
Description the 6f12p wideband triodepentode has been designed for use in frequency converting stages and highfrequency or lowfrequency amplifiers.

As of 3505, i have finished scanning the general section, receiving tubes part 1, receiving tubes part 2, miscellaneous, specialpurpose receivingtype tubes, thyratron, ignitron, and glowdischarge tubes, and most of the transmitting tubes, as well as all. The tube list at abc vacuum tubes is very extensive, as is our inventory of vacuum tubes, grid caps, sockets, valves and capacitors. The radio in question is an oldstyle regen using a single 12af6 pentode. Vacuum tube 12af6, pentode miniature pentode intended for use as a radio frequency or intermediate frequency amplifier in automobile radio receivers. The 12a6 was designed for use in the single end audio output stages of radio receivers. Index matching tubes index all tubes tube database search page 1 of 2. Double triode, 6h8c datasheet, 6h8c circuit, 6h8c data sheet. Herein you will find a collection of vintage engineering texts, vacuum tube datasheets, and other obsolete information, presented free of charge and without annoying advertisements. The kenwood ts830 uses one for a driver and that is early 1980s.
Subminiature tubes of the flat on inline contact type are tested in flat socket x109. Although originally marketed as pentode tubes for use in early television receivers, they found additional uses in audio and radiotelephone equipment. You can give them a try, but if you dont like a 12at7 subbed in whatever position you try, you will probably not like the 12av7. Bold designators are close or identical, italic designators are different ratings, different pinouts or different filament voltages. Rating sheets enables you to locate data by tube type tion and rating bears the.
Others may exist, especially from nonnorth american sources. The tube is specially designed to operate with plate and screen voltages supplied directly from a 12volt. In a few cases, when the 1966 edition omitted graphics on obsolete tubes, i inserted scans from the 1948 ginkins reference book. Nos tube specification sheet nos tube specification sheet. Data presented include those characteristics and ratings essential to fast. What got me looking more closely at the 6n7, besides zero bias modulator duty, is this old limiter. The thin metal tube envelope is 25 mm in diameter and, excluding the io base pins, is 67 mm tall. It is a little different than most and uses a 5814 which is a 12au7 in a bridge circuit the limiter used a 6n7 for this in early units. I am working on scanning and placing on this page the entire rca hb3 tube manual.
