The interstage transformer has to take some serious current, 3-5mA, which is not a small thing considering the signal amplitude. So they are size of output transformer, in 20, in the 86 - 112 radios, same thing.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
