I have a 110WPC amp that I have to replace the big filter caps on (old ones leaking). The caps are 15,000µf 80V. There is also an wierd steel bridge connectng the capacitor tabs on the common side. The only way to get this thing off is to cut it with a Dremel. I have a 75W solder gun and it won't even phase the solder on it, so I figure I'll cut the steel bridge that joins the caps for the common, and manufacture something to replace it with when I reassemble.
I have some 10ga bare wire. Thought I might use it to join the capacitor posts for the common, and solder all the ground connections coming from the output and the circuit boards to the middle of the 10ga wire...about equidistant from each cap terminal.
I guess my question is...do you suppose that a short length of 10ga solid wire is heavy enough to do the job? Should I try to run two pieces of the 10ga between the caps instead?
Thanks...

I'd be inclined to use two lengths as you suggest - any extra impedance at this point can cause distortion or instability.

I'd just do it and not bother to ask opinions, except that it will be a real tight fit to get two lengths of 10ga in there. I believe it can be done, but was wanting to see what the masses here at DIY thought.
shoot it in if ou can...the more the merrier...but it might be difficult to get it in.,..as you mentioned...maybe a busbar might help??
