precise —PRODUCT INFORMATION— Page 1 11-67 wren) Compactron 6BFII TUBES Dissimilar Double Pentode @ AUDIO POWER PENTODE @ QUADRATURE FM DETECTOR @LOW HUM @ 140 VOLTS B+ The 6BF11 is a compactron containing a sharp-cutoff, dual-control pentode (Section 2) and a power pentode (Section 1). The dual-control pentode is intended for use as an FM detector and the power pentode as an audio-frequency output amplifier in television receivers. The power output pentode features relatively high dynamic plate resistance which results in mini- mizing hum currents in the plate circuit due to power supply ripple.
