This is a V6 (not V3) chassis so the power regulator / modulator transistor is a TIP36 rather than a 2SB. Although they certainly are a common source of problems, the radio in this case is still working in AM and FM TX modes, in which that transistor also controls the supply voltage to the transmitter. See all earlier posts in the thread.
