Capacitors for Crossover

[MNYankee]

Hi, I am wanting to do a minor upgrade of the caps and resistors in a pair of PSB B6 speakers just for fun. The crossover uses 15uf 100v and 12uf 100v electrolytics.

My question is, can I use non electrolytic film caps with the same capacitance but higher voltage, say 250v to 400v?

I am also replacing the cheap sandcast resistors with Mills of the same values.

Thanks!

yes you can- but if you find 'em with 100 VL it's ok

Thanks. I was thinking of going with these from parts express to keep things cheap-

They will need to be mounted off the board.

100v 15uf and 12uf non electrolytic caps are hard to find.

Try looking through the following site. They have 10/12uf in 400v.

I ended up buying 15uf 250v and 10uf 250v Claritycap CSA's and Mills resistors. It should make a nice improvement in sound over the stock cheap electrolytic caps and sandcast resistors but you never know when swapping parts.

Any recommendations on hook up wire? I was thinking about duelund cotton in oil.
