Altec 19 ground mod

Hi everyone,

I've had my M19s for about 6 or so years now and they are from 1978. I've read about the ground mod and wondered if it was OK to try a temporary way to bypass the lugs before soldering. I haven't taken out my crossovers yet (that's this weekend's project), but I've noticed from pictures that most have "pins" that stick up from the board that it looks like the lugs ground to. Can I wrap wire around the "pins" at the lug points before soldering to make sure it has the intended improvement?

Thanks!
