It’s inside the styrofoam block.
It’s inside a sealed can in the block
It’s (maybe) inside a can inside that one.
It’s a SMT part on a board in that can.
You set the frequency by pulling what they have there, measuring it and
putting in another cap. If they used a series like 0.47 pf, 0.56 pf, 0.68 pf you may
not have them on the shelf.
