PrimaLuna Premium tubes selection

This listing brings together a selection of replacement tubes from the PrimaLuna brand, intended for valve amplifiers and integrated amplifiers originally fitted with this type of component. The tubes on offer cover several common uses on this type of unit: power (EL34, KT120, KT150) and preamplification (12AX7, 12AU7, 5AR4).

PrimaLuna distinguishes two selection levels. Silver Label tubes undergo a sorting process that rejects 40% of production, a level of control that matches the original equipment fitted to the brand's amplifiers and integrated amplifiers. Gold Label tubes undergo stricter sorting and measurement, rejecting 60% of production, aiming for greater consistency between the tubes retained.

A matching option (Match) is available per tube, allowing pairs or sets of tubes with close electrical characteristics to be assembled, an important point for power stages operating in push-pull configuration.

This selection is aimed at owners of PrimaLuna valve amplifiers, or any unit using the same tube types, wishing to replace an ageing or faulty set with new components from the same brand as the original equipment.

On a valve amplifier, buying new tubes remains the safest way to restore original performance, as tubes are wear components whose characteristics drift over time and hours of operation. The exact tube type (EL34, KT120, KT150, 12AX7, 12AU7, 5AR4) should be checked for compatibility with the unit concerned before any replacement, along with the possible need for a bias adjustment after changing the power tubes.
