EL84 Brimar N709 UK made 6BQ5 two rods supporting a single round getter

Brimar EL84 6BQ5 £ 120 quartet


The Brimar 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 Brimar EL84 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.
