Description

Selected power tubes
quartet (RT824)
Sold in sets of 4 valves

The TAD KT66 power valve is our reissue of the legendary British KT66 tube from MOV (MO Valve), GEC, Genalex and Gold Lion. This tube is a true reference. It has a large curved glass envelope and a rounded brown base. It helped make the Marshall JTM45 Plexi amps famous in the 1960s and made Quad Hi-Fi amps a legend.

Speaking of legends: SRV used the KT66 in his Fender amps to get his colossal, powerful guitar sound.

Height of the power valve (excluding pins): approx. 115 mm.

Recommended for :
a rich, thick sound with great dynamics, smooth but precise highs, single-channel amps, dynamic playing, vintage British rock and roll, as well as the new modern vintage 2266 and 2466 amps.
It can also replace 6L6GC and 5881 tubes.
