You could probably use a 112 for an output tube for increased power, but you would have to play around with the voltages a bit. What are you going to use for a speaker? Or are you going to use headphones?
Before powering up, you might want to test the windings on the audio transformers to make sure there are no opens, and check the grid-leak resistor as well (should be very high resistance, like 2 - 5 megs). Otherwise you'll be hearing silence!
