Genuine Mullard 12AX7s, have the special tube code on the side. These well made British tubes can now be yours, get them before they're all gone!
Standard Grade tubes are our most economical tubes, yet still a product of selection. In fact, it easily outperforms the best tubes offered by other companies. Only 40% of the tubes we test perform well enough to be considered Standard Grade.
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.
Large Inventory allows precision matching
Our standard grade is fine for power amp input stages and second stages in phono and line amps. When you buy a tube on eBay you have no guarantee of noise or microphonics.
