Why Use a Matched Pair or matched Quad of Valves?

In a guitar amplifier with two output valves, in simple terms, one valve is pushing the speaker cone and one is pulling it. In an amp with four output valves, the same applies but the amp has twice the power. With the same signal applied to each valve in the pair, you can see that it’s important that each valve gives an identical amount of push or pull. If this was not the case, sound fidelity would be lost.

So you MUST replace all the output tubes at the same time and you should buy your EL84 matched quad from a reputable dealer. At AmpValves we carefully test and match by hand every single valve. A matched pair or quad means each valve gives the same bias current under identical conditions of plate voltage and grid bias voltage.

These superb amplifier valves fit many different guitar amplifiers produced by a variety of different manufacturers. EL84 valves have a very specific sound so please check the exact valves you need for your amplifier by clicking here.

  1. George Henderson

    Fitted these today – awesome difference. But then my previous set were 6 years old! Thanks.

  2. Dan West (verified owner)

    Bought these for my AC30 C2. Been using it about twice a week for four years with the original Chinese stock valves – needed replacing after it started making a right horrible noise every time it was warming up.
    These JJs are a great replacement. It’s much clearer, not too bright or harsh and the volume’s increased.

  3. James Thain (verified owner)

    Great Valves fitted them into my Jackson Ampworks Newcastle 30. Great service from ampvalves too really quick delivery. Just spot on !

  4. Richard George

    Thank you for the great service. Fitted the valves yesterday and biased them, my Marshall Stack sounds brand new! I would recommend AmpValve to all.
