Does 840 have a pad? Is it live to the sink maybe?

Yes have a pad, it's transparent so you can't see, I measued for continuity between heatsink & 840, meter measures no continuity.

Lets knock down some resistance on that 47R to see if it draws more. Having another one to solder on top of it?

The one 47R you substituted for the trimmer, lets make it smaller by paralleling another one on top of it.
