Even the 5 amp spec is a little on the weak side, as the heater currents add up to about 5.25 amps. I suspect that it is the same xfmr used in the 173 and 183 and a couple more tubes were added in the 183D (double conversion) design. No worry there, as xfmr ratings of that era tend to be quite conservative.
