That all looks OK apart from the last test. I'm surprised that you didn't get a reading on the 20mA range. 0.01 amps is 10mA, so I would have expected to see a reading on the 20mA range. I assume the set was turned on? Are the normal sockets the ones to be used on the 10mA range?

I guess the next thing to do is fit the output transistors. Then switch on whilst monitoring the current drawn from the battery. If OK check the voltages on the output transistors.
