When ASMs/CPCs and TRKs (anyone know if Paulson's too?) first get produced and packaged for delivery they have a light chalk dust around the edges, I presume from the final lathe step. So if they are still chalky they have barely been handled since leaving the factory.
Looks like @Rhodeman77 has finished his set for the moment.
I think I‘ll wait for my samples from marlow before I really start to invest in TRK’s.
Hope it’s not the wrong decision to wait, because mostly it is the wrong to wait before start buying chips.
As I said in the next line of my post, TRK isn’t in business any more. There are no new chips being made by them. What is out there is all there will ever be. As more people want them they will become hard to find and or more expensive.
