Lundahl chokes are wound with two separate coils
which can be connected in series or in parallel.
The inductance and current values given below
are for the series connection. Parallel connection
will result in one quarter (1/4) of the inductance
at twice (2x) the current. This is because inductance
has a square relationship to the number of windings.
Doubling the windings results in 4 times the inductance.
All Lundahl chokes are wound in basically the
same way. This means that chokes labeled "anode
choke" can also be used as power supply chokes
and vice versa.
