Weller and Pace dealer.
There is a Precision Radio at 1160 King St. that sounds like the place.
Yes, they are an electronics parts supplier. They sell to all the folks
doing repair work in the state (and actually in a lot of the central
Pacific). They are the place to go when you need a 6DJ8 tube or a soldering
iron.
Check with the ohmmeter and see.
Are we talking continuity check between the pads that should not be connect=

And continuity check between the pads that ARE supposed to be connected.
You could have a solder bridge, then again you could have a cold joint.
The ohmmeter will tell you for sure.
Are you sure it's the same pad?
It's hard to tell through the 3x loupe what I'm looking at between the brok=

Anyway, I'm pretty sure I severed that line =

You overheated the board and lifted a pad. Now everything related to that
is going to have to come off the board, the lifted bit replaced with a piece
of hookup wire, and the whole thing put back together. It has just gone from
a relatively easy job with proper tools to a much more time-consuming and
difficult job.
