CV4043 - British-made miniature-tube 13.5W equivalent of the 6BW6, 9-pin base B9A. 6AQ5 - slightly lower specifications to the 6V6GT, miniature glass envelope, 7-pin base B7G. Other equivalents of this tube are the CV1862, EL90, 6005, 6095, 6669, 6928, BPM 04, CK-6005, M8249, N727, 6L31. 12AQ5 - Same as the 6AQ5, but with different heater ratings.
6P1P. The 6P1P (Russian: 6П1П) is a Soviet -made miniature 9-pin beam tetrode vacuum tube with ratings similar to the 6AQ5, EL90 and the 6V6. Because of a different pinout (a 9-pin base versus 7-pin base) than an 6AQ5/EL90, it cannot be used as a plug-in replacement for these types; however, it will work in the same circuit with component ...
V (Russian: В) – Vacuum tube with secondary emission. L (Russian: Л) – Nonode. Ye (Russian: Е) – Magic eye tube (e.g. used as a tuning indicator). U (Russian: У) – Power triode (was soon deprecated). The 3rd element is a number – a series designator that differentiates between different devices of the same type.
The CV2975 is the military designation (Common Tube) for EL84. [3] Other equivalent tubes are the 7189 and 7189A, [4] [5] an extended-ratings version of the tube for industrial applications, E84L (7320) long life, professional version with more than 10000 hours expected lifetime and the directly equivalent 6P14P (Cyrillic: 6П14П) produced in ...
Wherever possible, the 12V equivalent of a 6V tube had the same letters, just 12 instead of 6. L as a first letter often indicates a lock-in (Loktal) tube. P as a second letter from the end indicates a CRT. S as a first letter indicates single-ended tubes, related to grid-cap tubes. S as a second letter indicates single-ended tubes.
6AQ5. The 6AQ5[ 1] ( Mullard–Philips tube designation EL90) is a miniature 7-pin (B7G) audio power output pentode vacuum tube with ratings virtually identical to the 6V6 at 250 V. [ 2] It was commonly used as an output audio amplifier in tube TVs and radios. It was also used in transmitter circuits. [ 3] There are versions of this tube with ...
It is therefore inaccurate to say that these two tubes are identical. The correct Russian equivalent to the 6DJ8/ECC88 is the 6N23P, the latter has a S of 12.5 mA/V and a gain of 33. The closest western equivalent to the 6N1P is the well known 6BQ7A. A ruggedized/extended ratings version of the tube is designated 6N1P-EV (Russian: 6Н1П-ЕВ ...
6L6. 6L6 is the designator for a beam power tube introduced by Radio Corporation of America in April 1936 and marketed for application as a power amplifier for audio frequencies. [ 1][ 2] The 6L6 is a beam tetrode that utilizes formation of a low potential space charge region between the anode and screen grid to return anode secondary emission ...
