Video Amp Circuit Modification

By adding the capacitors you will have lost the DC component of the video signal. It may work with some video equipment if it's input circuit incudes DC restoration.

Also the capacitors are really too small - and probably not needed anyway, the input it's feeding 'should' have DC blocking, but AFTER the 75 ohm load resistor, this allows much smaller capacitors.

Hi,

If I remove the output capacitors & by mistake if I short circuit the output to ground will it damage the transistor?

if you were to use 2N3904/3906 transistors here, the max Ic would be 200mA, so short circuits at the output wouldn't be a problem.
