Are the GEC KT66 tubes compatible with Marshall Amps?

These GEC KT66 valves are compatible with Marshall Amps and were widely used in Marshall Amps in the 1960s. The GEC KT66 tubes are actually the tubes that Jimi Hendrix and Eric Clapton used for their Marshall Amps when they were in their prime.

What type of sound do the KT66 tubes produce?

These tubes produce a tight sound that is also smooth and warm. They offer mid- and top-end chiming and can make your guitar heard over all the other instruments.

How long is the life of these unused tubes?

While many of the KT66 tubes sold on eBay are unused, they are still vintage and have been stored for many years. The life length may depend on the amount of time they were stored for, and they may have slightly less than a full life left. The life length varies, but you can find many that have at least 97% of the life remaining.
