Looks an awful lot like an amplifier to me.
it is one of 3 rgb video buffers.......
Looks like an attenuator to me.
I was thinking R4 had some magical aspect.
What is the point of this post? Where did you get this circuit? I don't think this will work as an RGB buffer.
this was taken from a crt tv -the model escapes me at the moment where the fault was due to an oc inductor causing loss of one rgb signal at the scart socket due to a sc BC848 transistor i do have the manual on the pc somewhere
