what was used to stick it inside the case. The HTF is double-sided tape
stuck to the PC board, I'm afraid I'd wreck the HTF chip prying it up. If
I can't figure it out, I'll pry it up.
The leads were already disconnected, but I remember them being near J908,
99% certain about that because the way the leads were dressed.
