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

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
Rear shot, damage is in the bottom right corner.

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

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
