NOS - NEW OLD STOCK
Important: The sound of a tube-amp can be moddified - more or less, based upon the kind of tube-amp - with the use of different pre-amp and powertubes. To get an idea which tube combination is usefull for which purpose please see the TT Tube-Map: http://www.tube-town.net/info/doc/tt-tubemap.pdf or for Marshall and Marshall-Like Amps http://www.tube-town.net/info/doc/tt-tubemap-marshall.pdf Also feel free to visit our Forum for more help and support: http://www.tube-town.de/ttforum/index.php All powertubes will get shipped matched while note noted otherwise. If one orders more than one piece of the same type/brand it will get shipped matched. We do not supply any "matched" preamp tubes because this is in most cases not needed
