General Electric's Power Groove tubes For T2–T12 and T17, the number indicates the tube diameter in 1 ⁄ 8 inches, e.g. T2 → 2 ⁄ 8 in and T17 → 17 ⁄ 8 in. Whereas for T16 and T26–T38, the number indicates the approximate tube diameter in millimeters.
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...
12AX7 (also known as ECC83 [1]) is a miniature dual-triode vacuum tube with high voltage gain.Developed around 1946 by RCA engineers [2] in Camden, New Jersey, under developmental number A-4522, it was released for public sale under the 12AX7 identifier on September 15, 1947.
A compactron used in television sets to supply power to the anode of the picture tube. This tube is very rare, and very special, because it implements an indirectly heated cathode, not connected to the filament. No data is found on this tube, except for the filament power (which is 3.6 volts, 0.225 amps) and the base (which is the 12GQ type).
Tube weight was reduced by 31% when copper tube diameters were downsized from 3/8 inch to 7 mm. Tube weight was reduced by 46% when copper tube diameters were downsized from 3/8 inch to 5 mm. The weights of the fin materials in the coils was 3.55 kg for the 9.52 mm coils, 2.61 kg for the 7 mm coils, and 1.55 kg for the 5 mm coils.
A set of three matched Groove Tubes 12AX7 preamp tubes and two matched Groove Tubes EL84 power tubes, graded according to Fender's specifications, are used in all factory Blues Juniors. The Blues Junior uses a nonadjustable power tube bias (no way to vary the bias point), but it is fairly "hot" and can accommodate most matched pairs on the market.
An active-duty Marine was recently arrested after Google searches led Florida investigators to suspect he murdered a reality TV star and dumped her body in an Alabama pond. Willie Ellington, 20 ...
The 6V6 is a beam-power tetrode vacuum tube. The first of this family of tubes to be introduced was the 6V6G by Ken-Rad Tube & Lamp Corporation in late 1936, [1] with the availability by December of both Ken-Rad and Raytheon 6V6G tubes announced. [2] It is still in use in audio applications, especially electric guitar amplifiers. [3]
