Thanks for your answers :)   Now I have to wait for the burn in of these 3 pairs of tubes that I have (it will take a long time if I have to wait for 100h for each pair...) and after I will try to give my opinion about the sound if I can see a difference ! ^^ (and also if I can translate it in...

Hello all,   I've received a pair of Svetlana 6J1P-E of 1966, with 2 pairs of Voskhod 6ZH1P-EV, one from 1978 and one from 1981.   I have to burn in all of them, but I don't know the Svetlana, the seller has put it as a gift in the package, do you know them ? What kind of sound compared to...

  Yes in fact I get this information after ordering a matched pair, but for next time I will be aware of that and I will not make the mistake anymore :)

Ok thanks for your answers :)   So I'm waiting for a pair of matched Voskhod as the one that I ordered was not, and I will do the "cooking" of the Voskhof directly with these matched pair. ;)

Thanks for your answers. For the burn in, do I need to put sound coming to the LD ? Or just switching the amp ON is ok ?
