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.
The amplification factor of 6N2P is 98 which is marginally lesser than 12AX7, its higher heater current draw is similar to a 5751. The Chinese 6N4 (whose military issued variant is known by the designation 6N4-J) which is a pin-compatible replacement for the 12AX7 but has an amplification factor of 97.5 is the closest equivalent to the 6N2P.
This base type was used by many of the United States and most of the European tubes, e.g., 12AX7-ECC83, EF86 and EL84, produced commercially towards the end of the era before transistors largely displaced their use. The IEC 67-I-12a specification calls for a 36-degree angle between the nine pins of 1.016 mm thickness, in an arc of diameter 11. ...
It belongs to a large family of dual triode vacuum tubes which share the same pinout (EIA 9A), including in particular the very commonly used low-mu 12AU7 and high-mu 12AX7. The 12AT7 has somewhat lower voltage gain than the 12AX7, but higher transconductance and plate current, which makes it suitable for high-frequency applications.
The 12AU7 and its variants are miniature nine-pin (B9A base) medium-gain dual-triode vacuum tubes.It belongs to a large family of dual-triode vacuum tubes which share the same pinout (RETMA 9A).
The HDP-2200 Future Offshore Patrol Vessel is a class of six (6) offshore patrol vessels designed and built by Hyundai Heavy Industries (HHI) for the Philippine Navy.. The Philippine Navy is expecting the delivery of six new offshore patrol vessels acquired under its Offshore Patrol Vessel Acquisition Project under the Revised AFP Modernization Program's Horizon 2 phase covering years 2018 to ...
2012 Honda PCX 150. For 2012, the PCX 150 was launched in Australia. [12] The US skipped the 2012 PCX 125 as they made a switch for the PCX 150 model which arrived in the summer of 2012, these were later sold in 2013 for both Canadian and US markets.
The front carpet mats were inlaid with rectangular silver-coloured "Coupe F2" badges. According to the Hyundai Coupe F2 brochure, total on-the-road price was £17,999 (as of July 1998). [8] Two further items were available free to the first five-hundred Hyundai Coupe F2 buyers.
