Description:
Miniature types used as phase inverters or twin resistance-coupled amplifiers in radio equipment.
Application note :
This tube can be used without precautions against microphony in equipment which is characterized by Vi ≥ 10mV for an output of 50mW (or Vi ≥ 100mV for 5W output), provided that average acceleration of the tube is not greater than indicated in the Section “Microphonic effect” from the “Application directions”. In this case the disturbance level for hum and noise will be better than -60dB when the center tap of the heater has been grounded, Rg≤0,5MΩ and Rk is sufficiently decoupled.
Quick reference data :
• Anode current Ia=1,2mA
• Transcoductance S=1,6mA/V
• Amplification μ=100
