I wouldn't necessarily say the problem was in the output stage. Have you aligned it yet? At least do an IF alignment and see if you improve the volume.

I wouldn't think the 110 uuf caps would hurt your volume as long as they are connected right and aren't shorted. You can detect a shorted or a leaky cap pretty easily with an ohm meter.

If your meter measures capacitance you might be able to measure the capacitance to see if it is approximately what it's supposed to be, though the lead capacitance will interfere with your measurement. You can compare with a known good 110 uuf if you have one and see if it's in the same ballpark, or you can short your leads to approximate the lead capacitance and then subtract. If you're suspicious that the two caps are way off, it might be a good enough measurement.
