The capacitors that are used in this ATU are CMB-443BF’s. You can find them on AliExpress.

These capacitors are used for AM / FM receivers and have a total of 4 variable capacitances (hence the name poly capacitor). 2 x 266 pF and 2 x 20 pF. We only need the 2 x 266 pF for this project, so we are going to cut off the unneeded leads of the capacitor.

On the left, only keep the top short lead.
On the right, keep the two top leads.

Now it’s also a good time to bend the leads so they face downwards. The need to be downwards to be able to fit them in the enclosure. Be careful not to break them.
