    Not maybe, they are 100% fixable Take it from me that there are 101 ways of getting round a damaged PCB track

    So that's that worry out of the way

    Yup, and the best way is not to use any in the first place and hard-wire all the crossover components together instead!

I am hoping that the damaged board may be salvageable by using some form of connector between the caps but have decided to leave this until I can get someone who knows what they are doing to look at them.
    Email me some pics if you can. I need pics of both sides of the PCB. After I have studied the pics I'll let you know if and when you can send them to me for corrective action. Or pass by with them .

    Hi Stan, many thanks for the kind offer of help.

    The problem I will have is that once the crossovers are repaired the speaker wiring will need re-soldering in place and I am not confident that I would be able to do this. A fellow forumer has recommended a repairer who may be able to assist and is within traveling distance. If he is willing to have the complete speakers to work on then this may be the easiest option as he will also then be able to re attach or replace the wiring. I will contact him early in January to see if he can assist, if not then I will gladly be in touch.

    Below are the photos you requstested, one cap has still to be replaced. Those of a nervous disposition may wish to overt their eyes

    Easy as pie 1 minute job even allowing for the soldering iron to heat up

    Pity you weren't nearer, I'd do the lot for you including refitting the crossovers etc for a tinnie

    Bests, Mark

    No problem, Mothman, I actually forgot what my question for you was. I'm sure you'll find someone to do the soldering for you.

    Oh yes, I remembered! Mothman, have you sketched out the Xover schematic and have you recorded the element values? Not all cap and resistor markings are clearly visible in your original pic, and the caps in the new pic are too shiny.

    Hi Kai

    Below is a list of caps that I ordered to do both crossovers

    http://www.falconacoustics.co.uk/alc...-loss-50v.html

    Alcap 4.00uF Low Loss 50VDC Electrolytic Capacitor
    Capacitor Tolerance 5% Qty 4

    Alcap 8.00uF Low Loss 50VDC Electrolytic Capacitor
    Capacitor Tolerance 5% Qty 2

    Alcap 12.00uF Low Loss 50VDC Electrolytic Capacitor
    Capacitor Tolerance 2% Qty 2

    Alcap 16.00uF Low Loss 50VDC Electrolytic Capacitor
    Capacitor Tolerance 2% Qty 2

    I have not yet acquired replacements for the small 0.33uf caps, hopefully the tech who makes good my handy work will be able to source these.

    Hope this helps
    Rich
