The plate choke, as used in an HF tube type amplifier in this article. The plate choke is a device which serves the purpose of feeding the DC plate current back to the HV power supply, while blocking the passage of RF current. Since DC current only travels from negative to positive voltage potentials, the plate choke is in the return path for the current that has done the work of …

Chokes, mostly used in tube amplifiers. We have a wide range of chokes and inductors for tube amplifiers, ranging from anode choke LL1667 (operating current from 5 mA) to filament current choke LL7233 operating at 3.4 A. Our chokes are built in our dual coil single C-core style. The use of C-cores with well-defined air-gap results in an almost constant inductance throughout the …

•Common Mode Choke on transmission line to house had no effect •Caps (180 pF) on speaker terminals on audio amp made problem worse •Caution: dont use large caps (ie., 0.01 uF) with solid state amps => damage •Disconnecting 4 of 5 speakers from the audio amp eliminated problem •The two speakers with the longest cables were picking up RF

Gyrator plate load and gyrator instead of a power filter choke are very different beasts. The first is a good improvement, the second is suboptimal. Beauty of PS filter choke is, it stores an energy. High impedance in frequency band of amplified signal is it's minus.

A CLC filter operates the choke with a relatively low Vac, meaning the operating point is out at the DC biased region and oscillates around the DC point in a minor loop that causes the choke to present a certain level of incremental inductance - which generally starts to fall in value as the DC current gets larger and the operating BH region moves in to the saturation region.
