You can check the audio stages by touching pin 6 of the 1LD5 with the tip of a screwdriver that you are touching the screwdriver's shaft. If all is well you'll hear a loud buzz. Bare in mind that the buzz you'll be hearing is going to be as loud as the set will ever get is it should be rather robust. Portables generally aren't a loud a a 10 tube console with having the two 1LB4's in the output should be able to make about 1/2 watt of audio.
