OK. My experience with two baddest setscrews I had (one recent in Thorens idler)....still, PBBlaster. Soak it. Ot keep dripping on it every day. A few days needed. It WILL eventually turn.
But be careful, do not force, do not strip the slot.
Also: use a screwdriver with as blunt flat nose as possible to fit in that slot. Sharp one will bend, or will keep sliding out and wearing out that slot. The screwdriver should be just a tad larger then the length of the slot. Large handle to apply enough torque. And, blunt, blunt - cannot overemphasize it.
Again, keep dripping PBBlaster and wait a few days.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
