6AU6A / EF94 Realistic LIFETIME NOS NIB – Gold Clad Pins – Gray Plate – Halo Getter

AMPLITREX Tested – Gold Clad Pins – Realistic LIFETIME Original Box

Description

6AU6A / EF94 Realistic LIFETIME NOS NIB tube, supplied in its original box, selected for audio applications, radio, musical instruments, and compatible technical circuits requiring stability, good electrical quality, and careful construction.

The 6AU6A, equivalent to the EF94 family in compatible circuits, is a versatile miniature pentode, historically used in signal stages, vintage radios, audio equipment, and technical applications where good gain, controlled response, and operational reliability are required.

This version is particularly interesting due to the presence of Gold Clad Pins, a detail that adds constructive and collectible value compared to standard versions. The internal construction features a gray plate, top halo getter, and tidy structure. The glass is clean, the getter is intact, and the yellow Realistic LIFETIME silkscreen is still legible, with normal signs of age compatible with long vintage storage.

The tube is in NOS NIB – New Old Stock, New In Box condition, never used, and has been tested in our laboratory using the Amplitrex AT-1000 Tube Tester.

Sonically, it offers a balanced, clean, and well-controlled sound, with tidy bass, clear mids, composed highs, and a prompt dynamic response. In compatible audio circuits, it contributes to a stable, focused, and coherent presentation.

Suitable for equipment compatible with 6AU6A / EF94, vintage radios, audio circuits, signal stages, technical applications, instrument amplifiers, and restorations where a selected and verified miniature NOS tube is required.

A 6AU6A Realistic LIFETIME NOS NIB Gold Clad Pins truly tested by Vacuum Tubes Treasures, ideal for those seeking a well-preserved vintage small tube, with original box, careful construction, and authentic technical charm.

    Please understand that the writing on the glass of vintage valves has become very delicate over the years and comes off easily. You must handle them with extreme care to avoid this. Wear and damage to the writing on the valves reduces their market value and causes damage. Please exercise extreme caution.
