Our Low Noise tubes are a superior tube especially tested for today's quality line stages. Only 30% of the tubes we test perform well enough to be considered Low Noise. Some tubes may have branding that is not perfect, some lettering or logos may be missing or incomplete. Due to the rarity of new-in-the-box tubes, we can only supply tubes with low hours of use. They may have other markings such as Dynaco, Fisher, Heath, McIntosh. As an alternative we have the now rare Tungsram and equally rare Electronska (EI) from before the conflict when the plant shut down. We feel the pre-conflict ones are better to than the current production. |
