Hi Steve,

I just get reply from our engineers.
The value of R1 and C5 on SB-3680 are as following:
(1) R1: 0805/2.2K
(2) C5: it should be 33pF/0805, if you want to have 4.43MHz subcarrier

Engineers also provide me the value of the following:
(3) C9: 15pF/0805
(4) L2:  You are right.  It s value right now is 100uH, but if you want to 
have PAL system is should be 82uH.

Hope these information are helpful for you.

If you have any question, please feel free to contact us.

Thank you and have a nice day!
