Thanks all.

According to that PDF, C1 may be bulging at the top. However my C1 looks different, has a wire going from the top to the base, surrounded by hot glue. Maybe been replaced before? I'll take pictures tomorrow.

I'll also try resoldering j1 tomorrow. I've never desoldered anything but I have a desolder pump. I assume I heat the old solder, use the pump to lift, then plant down fresh solder?

thanks!
