It can also replace the 6L6GC and 5881 tubes.
Sound wonderful in my Quad 11 mono blocks. Large sound...detailed high end. Making my ESL 57's sounding VERY special.
Great service from Tube Amp Doctor.
The pair of TAD KT66 valves that I have are one of the best matched pair of power valves in my collection. In my Marshall JTM45 there is less than one milliamp between them. The sound is brassy and imposing with a good tight bass and yet sweet, detailed and easy to listen to. I have both the old stock GEC and the new Gold Lion KT66. The TAD KT66 that I have are more than a match for those and any other KT66 on the market.
They sound great in my Quad II amps.
KT66 sound - that`s it for the money, look no further
Amazing sound on my JTM45
one of the very best current production kt66s. after testing two pairs of these in two jtm45 and a komet 60 (as well as various plexis), I ended up preferring these tubes over the gold lions by a small margin. I also comparred the sound to two pairs of shuguangs that appear to be made at the same factory but ended up clearly preferring the TADs, since they sound more like the original GECs. by comparison, the tung-sol sounds like a 6l6gc
