OOPS - I see the DC restorer is not feeding the sync separator. But since it is AC coupled to start with, you do not need one in your circuit for that purpose.
Got my wires crossed and I now see the DC restorer is for the video - this also means you don't need one in your amplifier circuit.

By the way, where are you getting the 12 V supply for the amplifier? Any hum, noise or instability of the supply will transfer directly to the output on the collector.
