Isolation Transformers
Small choke coil for the front stage of the electron tube EI35 iron core is fixed by the horse clip. There are many varieties of enameled wire. It is used for the high-pressure filtering of the electron tube.
Bile pre-stage high-pressure choke: fixed by riding clip, EI35 pieces, stack thickness 15mm, choke including fixing frame size: high 32mm long 37mm thick 17.5mm, oxygen-free copper wire winding There is a gap between the E-sheet and the mat paper to prevent the iron core from magnetic saturation, and it weighs about 0.134Kg.

Introduction of low-frequency choke coils --- Low-frequency choke coils are often used to filter power supply of amplifiers. It has a large resistance to alternating current. The silicon steel sheet forms an iron core with an air gap to reduce magnetic saturation. Features: The use of inductance with large self-inductance coefficient and small resistance has great obstacles to low-frequency alternating current and gr
