EL84 Mullard Yellow print 6BQ5 Made in Great Britain code on glass rx2

Mullard EL84 Yellow print code rx2 B £ 180 quartet


The Mullard EL84 is in the miniature all-glass range having a single-ended construction and a B9A noval base.
With the maximum anode dissipation rating of 12 watts and a mutual conductance of over 11 mA/V a signal of very small amplitude is sufficient for full drive an amplifier. The Mullard EL84 GEC (N709) has been designed to satisfy demands in high fidelity in amplifier or receiver operation. To meet the requirements for high fidelity it is desirable to increase the available audio output power from the amplifier and hence decrease the distortion present at a given output, this is what the EL84 does.
