4 x 6550 Valves: Why Use a Matched Quad of 6550 Valves?

If you have four output valves/tubes, in simple terms, two valves are “pushing” the speaker cone and two are “pulling” it. So in an amp with two output valves, the same applies but the amp will only have half the power. With the same signal applied to each valve in the quad, it’s important that each valve gives an identical amount of push or pull. If this was not the case, sound fidelity, or tone, would be lost.

For a guitarist the tone is everything. Please note that valves (even the same make, same type) can differ wildly in their characteristics. That’s why this matching is so important. So you MUST replace all four output tubes at the same time.
