Grid choke LL1670
The LL1667 is a small size, high inductance grid choke for tube amplifiers. The choke is built with two coils and is
using one of our own special audio C-cores. The coils is wound using a low capacitance coil winding technique. The two
coil structure greatly reduces the risk of picking up hum caused by external magnetic fields from e.g. mains
transformers.
