JJ KT66 Singles Matched Sets Premium Tested
The JJ KT66 Singles Matched sets  are an ideal replacement in higher power amps. We offer single valves,pairs, and quads. This is one big bottle packing a lot of output power!!
Our Premium testing is at real amp voltages on our custom designed tester. Our checks include listening to your KT66 for noise and microphonics.
Matched sets come with a test certificate showing the test conditions and results. Each valve and box is labelled with the test results for that valve including single valves.
As these are high-power valves, we recommend setting the bias to avoid reducing tone and valve longevity.
