| 2A3 Single Plate
NOS |
2A3 "Single" or
"Mono" Plate. This is the original version of the 2A3.
Most agree they sound the best. However, they carry a high price tag
due to their rarity and demand. Single Plate 2A3's were made by
Cunningham/RCA, Sylvania, Tung-Sol and Arcturus. NOS examples are
nearly impossible to find. You will need to call/email for prices and
availability. New Old Stock (NOS) |

| 2A3 Single Plate |
As above but
"Used Tested Good". Several in stock now. Sometimes pairs
are available. You will need to inquire about pairs, brands, etc.
Be careful about the Ebay peddlers here. Most people do not know how
to properly check a tube for gas as I do. Single plate 2A3's are very
often gassy and will not last long or work properly in most amps. |

| 2A3 RCA |
RCA brand 2A3 "dual plate".
Actually the term dual plate is a misnomer. There is only one plate,
but there are 2 sets of filaments and grids which share a common plate.
They really should be called "dual filament". These are known to be
great sounding tubes and are a good alternative to the very expensive single
plate version. These are "New Old Stock"

These are the same as the RCA's but
are other brands like Sylvania, GE, Raytheon, Tung-Sol, etc. They are
of the "dual filament" variety. Some actually have 2 completely
separate plates which are in parallel. You will need to specify which
style you want. Matching is available at $5 extra per tube.

| 5930/2A3W |
This is a special creation by
Sylvania. They are quite odd looking with very large brown bases and
stubby straight sided glass. If you are familiar with the 5932/6L6WGA,
they look almost the same. There aren't many of these around.

| 2A3H |
This is a bizarre version produced by
Raytheon. It has actually 3 filament/grid sections which are all in
parallel. I think the "H" means "high power" due to the extra
filament. Rarely available |
