An example of how to clean out old ferrofluid and replace it with new is given here:
Replace ferrofluid in tweeter - a B&W tweeter as an example

A suitable replacement tweeter for the one in the Heybrook HB1 is the Vifa D27TG or the Scanspeak D2606 9220.00
Vifa D27TG-35-06 Diameter 104mm
Scanspeak Discovery D2606/9220 00

Hi. Everything with tweeter its ok. They dont touch.
For now i go to gainclone. I check it.
How can I test it when he is connected?
When i check signal to speaker right have 1-1,8v. Left only 1.6 to 1.7v. When i give full power right have high olmost 150voltage. Left speaker have 1.6-1.9 v.
I think LM 3875 its damage.

Your Gainclone amplifier may have been damaged when you connected it to your newly obtained Heybrook HB1 speakers.
One of the crossovers originally had that stranded copper wire soldered in place - apparently to convert the bi-wire terminals to single wire connection.
Connecting to the wrong terminals on that speaker would have short circuited that channel of your amp.
Anyway, as this now appears to be an amplifier problem, I suggest you close this thread and open a new one in the appropriate 'Amplifiers' section of the forum.

The attached diagrams show the difference between bi-wiring and single wiring.
The 'links' shown in the single wiring diagram can simply be short lengths of copper wire.
It is best to link the terminals outside the cabinet as shown. Linking them inside, as appears to have been done with one of your speakers, can lead to disaster!
If you understand that, then there's no need to post the photograph I asked for.

Please post a photograph of the terminal side (the side you plug the speakers cables into) of the crossover board so that I can instruct you correctly.
This side its ok?

I can't help but think there is some room for confusion here!
Compare the two attachments.
Note that the left hand board is wired correctly and that the right hand board is wired incorrectly (those thick copper wire links should not placed on this side of the board).
