Troubleshooting a faulty filter circuit in a PAL CRT display
This parallel resonant circuit includes both caps in parallel to tune at 6.0 MHz.  This is the sub-carrier channel in PAL for audio. 

Both C554 and C556 add in a shunt equivalent cct, (27pF) to resonate with (27uH), S555 in parallel, which is the ferrite tuning slug

The resistors form a 'T' pad attenuator to reduce reactive loading effects on previous source from shifting phase, while attenuating 18dB  then raising the load impedance on LC tank to reduce the resonant Q and increase bandwidth, BW of the tank circuit to about 1MHz.

Q = Xc(f)/Rp 



The R pad is necessary to prevent reactive loading effects ( phase shift) on the previous stage shared with video yet raises the source impedance to parallel resonance to reduce the Q and sensitivity to component tolerances or drift but resonance still provides a gain of 6dB with a -3dB BW of about 1MHz,

For it work as the Chroma Burst resonator, L555 must be around 52uH
