How do I know what stamp option to choose if there is no marking on the channel balance?

If there is no marking on your old balance, then you will have to weigh your sash on a scale and refer to the chart shown on the balance's store page.

If a sash weight is very close to the next level up, is it better to go with the heavier option?

No, not necessarily. You don't want a balance that is too strong.

The sash weight is 13.8 which falls in the 1930 category but close to 1940. Which would you recommend?

I would replace with the option 1930 unless the original balance was stamped with another number.
