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.
Also, the size of the aluminum wire needs to be larger compared to copper wire used for the same circuit due to the increased resistance of the aluminum alloys. For example, a 15 A branch circuit supplying standard lighting fixtures can be installed with either #14 AWG copper building wire or #12 AWG aluminum building wire according to the NEC ...
6262 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is related to 6162 aluminium alloy (Aluminum Association designations that only differ in the second digit are variations on the same alloy), but sees much more widespread use.
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.
Aluminum conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium , chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.
The head of a pike pole with various implements for pulling items The head of a short firefighter's pike pole. A pike pole is a long metal-topped wooden, aluminium or fiberglass pole used for reaching, hooking and/or pulling on another object. They are variously used in boating, construction, logging, rescue and recovery, power line maintenance ...
A utility pole, commonly referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole, telegraph pole, or telegraph post, is a column or post used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and ...
Making a ton of primary aluminum consumes at least 12,500 kW-hr, and most plants consume 14,500 to 15,000 kW-hr per ton of primary aluminum. [18] Secondary production of a given unit of aluminum requires about 10% of the electricity of primary production. The United States mined production of bauxite for primary aluminum production is ...
