The Czech/Slovak heritage of superior industrial craft continues with their line of Tesla tubes. The JJ KT-88 is superbly balanced with the mids sitting in the correct tonal position and providing plenty of detail. A nice warm bass response which is very tight and clear with plenty of depth and detail. When pushed in a Marshall, the JJ KT-88 will provide a superb creamy distortion.

All tubes are burned in, and then tested to insure accurate matching. Tubes are matched for current draw and transconductance, for maximum performance. Please vist our FAQ page for more details.
