RFCs

This is the filament RF Choke. This is a high current, low potential conduction path, is a 114A size toroid in 43 mix with 10 turns of 16 guage litzendraht wire. This measures at 110 microhenries

This is the plate RF Choke measuring at 1 milliHenry. It has very low current at very high potentials, and was purchased from surplus. Note the difference in windings, with very many turns of thin wire around an air core. Next to it is a .01uFd Silver Mica DC blocking capacitor. It is soviet military surplus and features high speed, low leakage and high stability.
