Can anyone recommend an A&P in the San Francisco Bay area that can do
static system checks at the owner's hangar?

There's a guy that operates out of the Nut Tree who probably could do
this. He travels to the Sacto area I know. Don't have his name or
number handy, if you can't get it elsewhere email and I'll get it for
you (fix my email address after you hit reply).
