Change C3 to whatever suits your fancy
Change C1 to whatever suits your fancy

Hi Jeffrey - Your advice is greatly appreciated.

RE: SoniCaps Gen 1 caps. They have a 3.6uF cap and a 6.8uF cap, but both are only 200V, whereas the stock Focal caps are 250V. So I assume that's not going to work.

RE: SoniCap Platinum caps. They don't come in the correct uF values, nor do I see any combination of 2 caps that sum to the correct values. Not to mention, they are, to use your phrase, more than I choose to afford. :-) I was hoping to do the whole project for $300-$500, so I need to find caps in the $100 range or so.

RE: MultiCaps RTX caps. Again, I don't see the correct values, nor do I see any combinations of 2 caps that sum to the correct values. Also, they tend to be 200V like the SoniCaps.

Hence the search for caps continues...

RE: Mills MRA-12 resistors. This is a stupid question, but I assume that replacing the stock 7 watt resistor with a 12 watt resistor is fine, provided that they have the same ohms rating (of 5.6). Is that correct?

Bryon

Jeffreybehr, have you tried Clarity's MR caps? The rest of Clarity's lines are mediocre in comparison. And as much as I like Sonic Caps, there is absolutely no comparison between Sonic Cap Gen I's and MR's.

Bryon, floating caps is fine as long as the leads are protected with shrink wrap, etc... The leads on MR's are generally pretty long.

See my thread on B&W 802 Xover mods. Just changed all the caps

More capacitor tests than you'd have thought possible.....

conclusion? Try for yourself.

Eld is correct. L6 is a roadblock inductor.
