Current savings by leaving out some parts?

[_]

I need a 2-channel video amp. I built a simple 4-channel one from a kit,
but as it will be battery powered it occurs to me that there might be some
saving of current by removing the transistors that drive two of the
channels. Is this right; would it have any unwanted effect on the
remaining channels, and if there would be a saving would it be of
sufficient size to bother?

I think it is quite possible. It is such a simple circuit
that you should trace it all out and draw a schematic.
Having that would make the answer obvious.

Is the device mounted on a heat sink a voltage regulator?
If so, you might be able to eliminate it and use a lower
voltage battery with no regulator loss.
