Lamordia mats droping completly randomly, or are some quest better to farm certain mats?

Pretty much as title says.

I've got 21 transformers, 48 resistors, 87 insulators and conductors.
Is there a quest/chest where transformers drop more frequently, or is it irrelevant as its just a random chance equal at all chests?

Transformers are the black pearl equivalents, so off the purples in the wilderness (and I assume the upcoming raid).

yeah I realised that after posting.
Too bad generic rare chests in wilderness only drop wires without secondary mats, unlike dread which dropped t-rex plus one of 4 mats
