TzeYang, I'm still amazed by how cleanly you can bridge that many pads. I played around with it a bit when I was reworking one part of my amp, and I think I'm starting to get a feel for doing it without wire jumpers to support the bridging. Do you do each pad one at a time, letting the solder cool for a moment before moving to the next one? I was able to get results closer to yours doing it that way, as opposed to trying to do several at once while the solder was still melted.
As an aside, today I finished applying the v3 revisions to both boards of my amp, and got things wired up temporarily for testing. Sounds great so far, and no more worries about bumping an alligator clip loose when I adjust the volume
I should have some more caps in on Tuesday so I can build the board for the ground channel.
