It would be a good sub for a 12at7 in bf amps to tame down the reverb driver side, or further. Shop our great selection of 6sn7, 5692, 6f8g, 6h8c, cv1988, cv278, ecc32 vacuum tubes now.
Nj7p tube database search there are a whole list of tubes that can potentially sub for the 6dj8 6922. This tube has a different pinout and cannot be used in 6bq5el84 sockets unless you have verified it will work. Essential characteristics, ge 1973 manufacturers literature. What tubes may be used interchangeably moreless with a circuit designed around the 6922 6dj8, 6bz7, 6bq7, 6h23, 7308, 6sn7, 6n23, 6n11, ecc88, e88cc, etc. Adjust the vr1 500ohm so that the the tube filament voltage middle pin of u1 is around 6. 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. In most cases the tubes manufactured to the european system have an exact equivalent tube in the american system and vice versa. Thanks to max, the chance i have it, has increased considerably. Twin triode, 12ax7 datasheet, 12ax7 circuit, 12ax7 data sheet. 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. Like the similar 6at6 this design specification was interpreted by several manufacturers. Etc, alldatasheet, datasheet, datasheet search site for electronic components and semiconductors. Hoping to get back to it soon but most parts are in stock including other circuit board supplies such as turrets and stakers. The el84 is smaller and more sensitive than the octal 6v6 that was widely used around the world until the 1960s.
Construction refers to both basing size and the envelope hf means heater or filament voltage and current specifications. The 6146w vacuum tube is a ruggedized military version of the 6146 family of tubes. The 6av6 was designed for signal detection, agc detection rectification and first audio voltage amplifier in superhet radio sets. To meet these demands, some truly awesome power tubes were developed for increased current sourcing, and power handling. The el84 is a thermionic valve of the power pentode type. This causes harmonics of the signal frequency to appear in the anode current. 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. During the 1950s, screen sizes and deflection angles increased, giving a larger viewing area, and a shorter crt for more compact tv sets. 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. Tube 6bq7 or rohre 6bq7 id3812, double triode, noval, b9a and vhf shown. Tube cross reference letter nostalgic kits central.
A valve like this would be used for rf amplification, or frequency multiplication. The 6bq7a is an all glass miniature vhf double triode and is internally screened. Nos rca 6bq7a 6bq7 matched triode tube perfect blackplates for schiit lyr amp. It has some 12% higher gain, the characteristics are otherwise the same. 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. Tube 6q7 or rohre 6q7 id963, double diodetriode, octal int. I realize this may be redundant of much earlier messages, but i would appreciate any guidance you can provide. It is used in the power output stages of audio amplifiers, most commonly now in guitar amplifiers, but originally in radios. The driver position does better with a 6n1p as it is an srpp circuit and can tax some tubes.
Diy audio projects forum new pp amplifier project 7551. We carry all of the major brands in nos, vintage and new production vacuum tubes. The spec sheet even includes a composite plate characteristic for cascode operation. I have never been one to follow specs or rules so i decided to turn up the voltage.
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. Applica tion is primarily intended for replacement in circuits requiring unusually low plate current operation, such as those employing the type 12ax7 vacuum tube. Nos rca 6bq7a 6bz7 matched triode tube perfect blackplates for schiit lyr amp. Shop our great selection of vt100, cv124, 5933, cv1060, cv1572, vt6, cv659, fu25, vacuum tubes now. The list includes the 6aq8 6bk7 6bc8 6bq7 6es8 6fw8 6bz7 6bz8. Our tubes are always tested, matched and guaranteed. To prevent damage to equipment, it would be wise to double check with a good tube manual before actually doing a substitution. Double triode, 6h8c datasheet, 6h8c circuit, 6h8c data sheet. Bold designators are close or identical, italic designators are different ratings, different pinouts or different filament voltages. 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. For other applications, refer to the ts12at7a1 fetron data sheet. The valve came in three heater versions the 3av6 at 3. Identical to the 6bq6ga except for heater ratings and addition of a controlled heaterwarmup characteristic. In the latter case the valve is operated as a nonlinear class c amplifier.
