My friend Vyacheslav sent me for testing an\u00a06P36S \/\u00a06\u041f36\u0421 <\/a>output beam tetrode which was used for TV horizontal deflection circuits in the old days. \u00a0Here are the nice curves in triode mode:<\/p>\n

\"6P36S<\/a>Low anode resistance and high current capability with its 12W of anode dissipation make this cheap indirectly heated tetrode an interesting candidate for an amplifier. Let’s have a look at the triode model:<\/p>\n

\"6P36S<\/a><\/p>\n

Happy to complete the triode SPICE model if someone can translate the Russian datasheet and provide me with the electrode capacitances.<\/p>\n

Well, how will this triode perform in a simple SE configuration? With a low Ra, a 5K anode impedance OT will work well:<\/p>\n

\"6P36S<\/a>With just 55Vpp we can drive this valve to produce 2W @ THD=1.6% (without considering the driver distortion cancellation). The valve can be biased nicely at 55mA and 220V.<\/p>\n
