  2. 12AX7 - Wikipedia

    en.wikipedia.org/wiki/12AX7

    The 12AX7 is a twin triode basically composed of two of the triodes from a 6AV6, a double diode triode. The 6AV6 is a miniature repackaging (with just a single cathode) of the triode and twin diodes from the octal 6SQ7 (a double-diode triode used in AM radios), which itself is very similar to the older type 75 triode-diode dating from 1930.

  3. List of vacuum tubes - Wikipedia

    en.wikipedia.org/wiki/List_of_vacuum_tubes

    High-power RF power tubes are directly heated; the heater voltage must be much smaller than the signal voltage on the grid and is therefore in the 5...25 V range, drawing up to hundreds of amperes from a suitable heater transformer. In some valve part number series, the voltage class of the heater is given in the part number, and a similar ...

  5. AGA cooker - Wikipedia

    en.wikipedia.org/wiki/AGA_cooker

    AGA's own figures for expected energy consumption for their two-oven model support this criticism, [7] suggesting average consumption of 40 litres (9 gal. imp.) of kerosene or diesel fuel per week, 60 litres (13 gal. imp.) of propane gas per week, 425 kW⋅h of natural gas per week, or 220 kW⋅h/week for the electric models. This would ...

  6. 6N2P - Wikipedia

    en.wikipedia.org/wiki/6N2P

    The most significant difference between the two is that 6N2P has its two filament elements connected in parallel, unlike the series filament connection of the 12AX7, and it is thus only possible to operate it from a 6.3 volt, 340 mA filament supply (whereas a 12AX7 may be operated from either 6.3 or 12.6 volts, at 300 mA or 150 mA, respectively.)
