  I stock three types of KTxx power tetrodes - also known as beam power tubes.

They are new production from JJ, Slovakia and Shuguang, China, and are clones of the English types KT66, KT77 and KT88.

The KT66 can also be used in 6L6 amps, if the power supply can supply the higher heater current (1.3A vs. 0.9A). The KT77 can also be used in EL34 amps and the KT88 tubes can also be used in 6550 amps.

Note: The tubes are supplied as matched pairs.
