Hey all,
I just have some simple questions about replacing crossover
components.
If you have prebuilt crossovers and you want to replace a
capacitor and you know the value and say it's a 40.0uf and
all you can find is a 39.0uf and a 1.0uf you can use the
pair together to make 40.0uf correct? The capacitance value
comes out the same by using two to arrive at the figure.
Next question...
Can an Iron Core Inductor be replaced with a regular Air
Core Inductor? Why would they use an I-Core and an Air core
on the same side of a board, was this done to thwart magneto
striction between two air core inductors?
Third question...
Say the Air Core Inductor you need is a 0.31mh and all you
can locate is a 0.33mh, can you unwind some of the windings
to get the 0.31mh figure? What do you need to test the inductor
with to make sure you arrive at that precise value?
And Fourth... Why in gods name is a 200.0uf Capacitor so
danged expensive.. YEESH $90.00 for a pair of Solen 200.0uf's
A rough shoppers list of components to rebuild my existing
XO's comes out to $256.16 from PE!
That's all Solen Caps, Dayton Non Inductive Resistors, Alpha
Foil Inductors (where I could find them that matched the
specs..)
Crossovers get pretty expensive it looks like
