Applica tion is primarily intended for replacement in circuits requiring unusually low plate current operation, such as those employing the type 12ax7 vacuum tube. The 6146w vacuum tube is a ruggedized military version of the 6146 family of tubes.

The resemblance between the two tubes actually ends with the 5pin socket and cap, among other reasons because the 307a is a true pentode unlike the 807 which is a beam tetrode tube.

The rca receiving tube manual does make a concession to this sort of usage, including the 6bq7 in its example designs for rc coupled voltage amps. The el84 is a thermionic valve of the power pentode type. It can flare brightly for a second or two before the rest of the filament has a chance to heat and develop enough resistance to limit the current. It is a small, sturdy, glassoctal heater cathode type used as an af power amplifier and modulator and as an af power amplifer and oscillator.

Nos rca 6bq7a 6bq7 matched triode tube perfect blackplates for schiit lyr amp. The 6n1p has similar ratings to the 6dj8 and in the past was sometimes rebranded as such, however differences between the two types the 6n1p requires almost. Gec, alldatasheet, datasheet, datasheet search site for electronic components and semiconductors. Cheap tubes and cheaply made tubes arent good tubes. Tube 6q7 or rohre 6q7 id963, double diodetriode, octal int. The valve came in three heater versions the 3av6 at 3. I have never been one to follow specs or rules so i decided to turn up the voltage. Bold designators are close or identical, italic designators are different ratings, different pinouts or different filament voltages. The driver position does better with a 6n1p as it is an srpp circuit and can tax some tubes. Like the similar 6at6 this design specification was interpreted by several manufacturers. The spec sheet even includes a composite plate characteristic for cascode operation.

Substitutes are given as a guide only please refer to original manufacturers data sheets to ensure that a substitute is safe and appropriate for your application. Replaced the 6bq7 within 2 years of the 6bq7 announcement. Nos rca 6bq7a 6bz7 matched triode tube perfect blackplates for schiit lyr amp. The 6bq7a is an all glass miniature vhf double triode and is internally screened. Nj7p tube database search there are a whole list of tubes that can potentially sub for the 6dj8 6922.

In the latter case the valve is operated as a nonlinear class c amplifier. Our tubes are always tested, matched and guaranteed. It has some 12% higher gain, the characteristics are.

Every effort has been made to insure the accuracy of this reference, however, i assume no liability for the results of using information contained herein. The el84 is smaller and more sensitive than the octal 6v6 that was widely used around the world until the 1960s. Identical to the 6bq6ga except for heater ratings and addition of a controlled heaterwarmup characteristic. A valve like this would be used for rf amplification, or frequency multiplication. During the 1950s, screen sizes and deflection angles increased, giving a larger viewing area, and a shorter crt for more compact tv sets. Tube cross reference letter nostalgic kits central. The 6dj8 is a frame grid sharp cutoff twin dual triode with separate cathodes originally intended for use as a cascode circuits, rf and if amplifiers, mixer and phase inverter stages. In most cases the tubes manufactured to the european system have an exact equivalent tube in the american system and vice versa. It has some 12% higher gain, the characteristics are otherwise the same. If everything is ok, the measured voltage of vcc terminals of r2 or r5 are about 65v dc.

It didnt sound half bad, in fact i think that it sounded better than the 6b4, but not as good as the 300b. With the very large number of vacuum tubes or thermionic valves that were produced and as a result of the multiple vacuum tube numbering systems that were in use, there are generally equivalents for most types of tube. The 6883b 8032a 8552 vacuum tube is a small, sturdy, glassoctal heater cathode type used as an af power amplifier and. Thanks to max, the chance i have it, has increased considerably. Hoping to get back to it soon but most parts are in stock including other circuit board supplies such as turrets and stakers. It would be a good sub for a 12at7 in bf amps to tame down the reverb driver side, or further. It would be a good sub for a 12at7 in bf amps to tame down the reverb driver side, or further tame down the ltp in bf. An interchangeable north american type is the 6bq5 the retma tube designation. To prevent damage to equipment, it would be wise to double check with a good tube manual before actually doing a substitution. To meet these demands, some truly awesome power tubes were developed for increased current sourcing, and power handling. It is used in the power output stages of audio amplifiers, most commonly now in guitar amplifiers, but originally in radios. Double triode, 6h8c datasheet, 6h8c circuit, 6h8c data sheet.
