Like I said, if he's got the right tools ...
I'm a degreed engineer; knowledge of what needs to be done isn't the

That's what I thought, too, and in fact I did accomplish it, but it took

I sent one in which had a bunch of bad caps and the manufacturer turned
it around in a couple of days for 20 bucks. I couldn't even see the
