The SF/SE had only one transistor if I recall correctly: the UHF oscillator.
I have an SF 12" portable hybrid set. It uses an IC for the audio circuit and a HV type audio transistor. It also has a FET for the horizontal osc transistor.
I'd have to review the schematic again. An interesting design, to be sure.
