I agree Plus Gas is a far better penetrant. I hope you are successful but if it has been stored a long time in the damp I`m afraid you have to expect a lot of trouble getting them off. Don`t try to drill out the grub screw unless you are absolutely certain it is not hardened steel. All that will happen is that you will blunt or break the drill and it will wander off centre and damage the knob.

The radio in question is just another of those Little Maestro styled kit radios.
I think it is a clause in Sods Law specifically related to radio restoration that there's always one knob with a frozen grub screw.
I have not encountered any with steel grub screws yet. As the radio has not yet been delivered I will get some Plus Gas.
I wanted to treat all 3 screws with the stuff as old brass gets brittle, and I didn't want to damage the screws.
