Does any members here know if there is retrace mod out there for the pilot tv like the one that is for the Motorola tabletop sets, the resistor and cap. Maybe something similar for the pilot ?

If you mean the TV-37, it has DC restoration, so that should
not be needed. I've never noticed any problems with mine.

Well it's the one without the ballast whatever that is as far as model go. It has the typical retrace lines like the Motorola sets have and lowering the bright they get less just like the motorolas.

The TV-37 has the same combination sync and DC restoration circuit as early Muntz sets. Judge for yourself whether you think DC restoration and prominent retrace are mutually exclusive....

About 3.5 minutes into this video he discusses and demonstrates the mod:
