Heresy 2 crossover

[Kriton]

I am lining up the winter projects and I want to do a recap of my beat up garage H2's, but I cannot tell what the cap values are supposed to be - I was going to attempt to just go ahead and rig them on the black binding post caps as they are now, but I might just go ahead and put a board together - lots of parts on these too that I don't understand as follows:

3 blue rectangular caps

1 blue "can" cap (and has "15k" stamped up the side)

as well as 1 square and 1 small round wound AF's (which don;t need replacing, or should I?)

If anyone could give me the schematics or tell me what the cap values are in this crossover I would appreciate it...

Thanks as usual Bob -

Couple of follow up questions, I know that you suggest not bothering

loading up the binding pole cap with all of this stuff and just putting

these things on boards, do you think it is worth while replacing the

tiny inductors on this crossover? Is it necessary? They do

not look as robust as the inductors on say my Cornwall crossovers, but

I don't know the difference - and why are there three on this

thing? If I wanted to replace the #3504 on the diagram, what

would I be looking for - eg. value of mH, etc?

I have seen that you are using Sonicaps now, do you have a H2 kit

available for the DYI crossovers? Board, inductors, caps and wire

harness? AND placement on board instructions? Just a

thought _ I would really like to upgrade my new Heresy 2's too one of

these days, but that is on a PCB on the square binding pole cap - I think a little easier.

Thanks again,

Kriton,

I would not replace the inductors. Won't hurt anything to replace them, but I don't think you will gain anything. If you go to a separate board, just make sure to mount the air core inductor far enough away from the other parts that they are not effected by the other components. Also if you do mount the coils on a board, use a brass or stainless screw through the center of them for mounting or glue them to the surface. A steel screw would change their values.

The 3504 is the autotransformer. It could be replaced with one of my 3636 autotransformers. As far as I know that is the only one that could replace it. The attenuation is 10 db.

I could make you up a kit with as much of the stuff as you want in the kit.
