These KT66 are almost a mixture with a 6L6. They're detailed, and clean with lots of headroom. They're also durable and good at dealing with a range of devices. A plus point is that they look fantasic too which is why they're often found on home audio systems almost as a display piece. Note - the bottom of the tube is slightly tapered so make sure it will fit your device (tube retainers need to be removed).
