Frazier Crossover Capacitors

Are these any good - are they the wax filled type - should they be replaced?

[DeanG Crossovers]

Yes, it's packed with wax. The price of an equivalent replacement would make your chest seize up. It looks clean, and as long as the wax isn't seeping through the cardboard tube or leaking out of the ends - leave it alone.

For a 3uF 50 volt cap?

[MZernial]

Thanks Dean, the speakers sound so good, I was told if they where wax-filled they would still be good.

[DeanG Crossovers]

I only know of one company that makes them. They make a 3.3uF, which costs $94.00. The 3.3uF is within 10% and close enough for low order filter, I get them matched to within 2%.

Jupiter Capacitors also make wax in paper and are highly thought of in audio circles

You will need to see if they make value you require

Are wax caps better or something?

I am surprised nobody has come in with replacing the caps with something more modern. If they were my Fraziers and those caps were bad, I would call Bob Crites and buy a set of Sonicaps.

There are differences in opinions everywhere about when to replace caps and when not to. The best advice I could give would be to buy a couple Sonicaps, and try them. If you hear a big difference, you will be glad you did it. If you do not, then you are out about $25, and you can solder the wax ones back in if they are indeed better. I buy stuff all the time and find out I didn't need it. The only true way to tell is to hear the difference.

[MZernial]

Yes, That is what I am going to do. Just received the Sonicaps today (4- 3.0 uF), I am going to replace in (1) speaker only for A/B compairison. Question, these are Mark IV's I have seen pic's with (2) 3.0 uF caps and mine only (1) 3.0 uF, which is correct? should I try both 6.0 uF and 3.0 uF?

The Electrocube caps were hard to beat.

They are a stacked-film type with hand-soldered teflon wire leads, in a paper tube filled with sand and sealed with wax.

I have never seen one fail.

The cap in the photo is not an Electrocube.

In the crossovers I currently use

The capacitors are a combination of Sonicap & Jensen Superior

However I just ordered 2 of the new Duelund cast hand made 10r10W resistors to give them a try

I mistakingly thought it was.

The cut sheet Chris put up says "metalized condenser".

I love the construction of the Jupiter Vintage Flat Stacks. I've started my own personal supply. I feel like I belong on an episode of "Hoarders".
