Buying a Matched Sextet 6 x 6550 Power Valves.

We sell the amazing JJ 6550 valves in matched sets of 6 (or 2 or 4). JJ is one of only five valve manufacturers in the world. So don’t pay more for rebranded versions of the exact same valve.
Why Use a Matched Set of 6550 Valves?
In a guitar amplifier with six output valves, in simple terms, three valves are pushing the speaker cone and two are pulling it. In an amp with two output valves, the same applies but the amp has one third the power. Four valves and you get 2/3rds of the power.
With the same signal applied, each valve gives an identical amount of push or pull when using a matched sextet of 6550. If this was not the case, fidelity would be lost.
So you MUST replace all six output tubes at the same time and you should buy your matched sextet of 6550 from a reputable dealer. At AmpValves we test all incoming stock and sort into a matched sextet of 6550. A matched sextet of 6550 means each valve gives the same bias current under identical conditions of plate voltage and grid bias voltage.
