Nearly all the Russian-made EL34 tubes are made by New Sensor, these include Svetlana, Mullard, Tung-sol, Electro-Harmonix, Gold Lion (KT77) and Telefunken with minor design changes.All the New Sensor tubes are superior to the Chinese El34s which do not last as long and sound harsher. Luckily, the EL34 tubes have not been stricken by the high prices like the KT88 tubes because of the Russo-Ukraine war. These tubes sound clean and smooth and is a great buy.
