| 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" Matching
available at $5 extra per tube |

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. "New Old Stock" |

| 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 |
