Classic chassis construction with point-to-point wiring. The right transformer is the power transformer, the left one is actually the coil in the audio oscillator tank (several mH).
Rectifier diode, selenium type. Big form factor.
Double triode 12BH7, used in the rf oscillator as colpitts oscillator and buffer.
Miniature power pentode 6AR5, as audio tone buffer or amplifier for external modulation signals.
LC-tank in rf oscillator. On the left hand side the switchable inductor section, on the right hand side the variable plate capacitor. Very wide straps of metal connect the two devices. Literally almost a tank.
