Is something brewing in the former Czechoslovakia? The whole country is the size of a half of New Jersey but they have 3 manufactures that do “objectionable” tube today. Is it the same rebranded group of people behind of all of them?
For those who do not know, Riccardo Kron and Alessa Vaic went into business to make tubes, this was the original Vaic company. They parted ways, and the designer, Vaic, formed the AVVT company. Meanwhile Kron formed the KR company and they both made similar tubes. Vaic, and later his other business partners, outsourced tube manufacture to the Slovakian Tesla factory, who also began to market the tubes under the JJ brand.

Are they all the same tubes? Not exactly, but honestly they are all quite similar. The KR tubes are the most robustly built and in my opinion have a clarity and focus to the sound that the others lack.

However all the 2A3 tubes are much better that the Chinese made tubes, which sound by comparison like a cat stuck in the mud howling.

I will soon be getting some new tubes which Romy pointed out and let you know how theses sound as well.
