I don't know about the restoration process. But, I can recommend a new
crystal element that is virtually indistinguishable from the old D104 in
output and tone. They are made by Kobitone and Mouser stocks them
(25LM024). The are only a few bucks each.

I have replaced many a D104 elements with them and have excellent results.
