About This Listing
One Matched Pair of JJ Electronic KT66's. The JJ KT66 is a spectacular sounding tube! It has a very thick and rich sound with lots of harmonic complexity and a wonderfully smooth breakup when driven into saturation. These are amazing in JTM 45's, 800 Marshalls, Dr Z RT 66's along with all the other classic KT66 applications. We are also using these in Mesa Single Rec's, Dual and Triple Rec's all by themselves and in combination with KT88's and 6L6GC's. We have researched the proper grades to get the bias right where is should be with no bias mod.
At Eurotubes there is no such thing as platinum matching or an upcharge for "closer matching" . All power tubes are matched within one milliamp period.
After a 24 hour burn-in all power tubes are tested for noise and matched at multiple operating points for plate current ( ± one milliamp) and transconductance. This is done on our custom made Kamna Matcher. The voltage is regulated to within a tenth of a volt and the high DC voltage is applied to all tubes simultaneously. The Kamna Matcher features individual readouts for each socket and each socket is fully active during the duration of the matching process which includes testing for current, transconductance and individual audio tests.
The video below shows both our preamp tube testing and power tube matching procedures here at Eurotubes which are second to none. We may not be the cheapest, but we are arguably the best.
