Vandersteen 5A's Internal crossovers/batteries

I forgot to ask that Richard in the manual says to use a soldering iron not a soldering gun. What do you suggest? I own a weller soldering gun.
Radio Shack has a 35 watt iron. Also should I use silver solder?

Thanks Alan

Thanks for all your help. Yes I agree that the soldergun tip might be too big. So to be on the safe side. I will buy a new 35 watt iron from Radio Shack and Silver solder from Music Direct.

Thanks again,

Alan

How much did Vandersteen charge to replace the batteries
for the pair?

Thanks for your help

Yes you're right. Thanks for advice.
