Why do these KT88 power valves need to be matched?
In a guitar amplifier with two output valves, one valve is “pushing” the speaker cone while one is “pulling” it. So, 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, it’s important that each valve gives an identical amount of push or pull. If this was not the case, sound fidelity and tone would be lost.
So you MUST replace both output tubes at the same time. At AmpValves we carefully select, test, grade and digitally match all stock before we ship to you.
A matched pair of KT88 power tubes means each tube gives the same bias current under identical conditions of plate voltage and grid bias voltage. Please note that valves (even the same make and same model) can differ significantly in their characteristics. So this is why matching the valves is so important.

The KT88 valve is a much sought after guitar amplifier valve.
It is highly regarded by guitarists around the world. The only reason that more amplifier manufacturers don’t use them is to keep down the costs, which is a real shame.
You can buy a new and tested matched pair of KT88 valves from us.
So we recommend that a set of matched valves are always used. This will ensure the best possible tone and power from your amplifier.
