Description	Miniature type used in light-weight, compact, portable, battery-operated receivers as combined detector and voltage amplifier. Filament 1.4 volts, 0.05 amperes. The 1U5 has the same electrical characteristics but it uses an improved structure which greatly reduces any tendency toward microphonic effects. In addition, the diode unit is effectively shielded from the pentode unit to prevent "play-through". They are not interchangeable since pin allocation is completely different
