There are two kinds of people.
The first kind sees an old glass tube.
The second kind immediately turns it around to check the valve number.
If you are in the second group, welcome. You are among friends.
Why vacuum tubes still matter
For many music lovers, musicians, restorers and hi-fi enthusiasts, vacuum tubes are more than components. They are part of the sound, character and experience of classic audio equipment.
From preamp valves such as the 12AX7 / ECC83 to power tubes such as the EL34, 6L6 and EL84, different valve types play a major role in amplifier performance and tonal character.
Looking for a specific valve?
Glass Audio stocks a selection of current-production vacuum tubes as well as New Old Stock (NOS) and Old Stock valves for hi-fi amplifiers, guitar amplifiers, vintage radios and restoration projects.
Our range includes popular and hard-to-find types, and our NOS and Old Stock collection may include valves from respected manufacturers such as Mullard, RCA, Philips, Brimar, GE and others, subject to availability.
NOS and Old Stock valve condition and availability can differ from item to item, so pricing is supplied on request where applicable.
The little ritual every valve person knows
You pick up the tube. You hold it toward the light. You rotate it slowly. You search for the number. Then you realise you have been examining a piece of glass for five minutes while everyone else in the room wonders what you are doing.
Perfectly normal behaviour.
