JJ
12AX7/ECC83S • $9.95
These JJ ECC83-S come stock in every single Swart amplifier,
from the ST-6V6se to the SST-30. For the Single-Ended amps like
the 6V6se, Atomic Jr, and STR variations, you might consider various
NOS options. The first driver tube is really important in all the
circuits. A 5751 brings slightly less gain. You're urged to experiment
with more compelling options but this is a great, all-around new version
of the 12AX7. ~ kh

JJ
12DW7/ECC832 • $12.95
The other stock tube in all Swart amplifiers with
that magic all tube/spring tank reverb. This is another relative
problem-free tube. On the other hand, there are some NOS 12DW7
floating about online for reasonable prices. We've not done
a a-b comparison but you're encourage to experiment. On the
other hand, this JJ is a safe, consistent bet. On the fly, a
stock 12AX7 will do for testing and emergency services but the 12DW7
is the proper fit. ~ kh

EH
6V6GT Matched Pair
•
$29.95
Since 2004, we have used a variety of new tube production
for our 6V6, from NOS Sylvania at the very beginning to EH, Ruby, Tung-Sol,
and JJ. The Tung-Sol turned into our favorites for quite a while
but the production has not been standing the high bias for that sweet
tone. Bottom Line, we don't recommend them unless an Ip of 30
or less. Of new stock, we've lately been happy with the current
runs of the EH 6V6GT. It's got some vintage sweetness though not
quite the output of the JJ. But it seems to get closer to the
T-S paradigm then the JJ as of late. ~ kh

JJ
6V6S Matched Pair
• $29.95
These are probably the most robust of the new 6V6,
almost in the low 6L6 spec range, sometimes sounding a bit closer to
their big brother then a vintage sounding 6V6 like the Tung-Sol.
Maybe the choice for the most clean headroom in a 6V6 but perhaps lacking
some of the soul of the others. Occasionally a rattle issue come
up but most can be solved with tube rings. They have gone out
with a lot of stock AST, AST PRO, AST Master, and SST. We still
use them and a safe choice. ~ kh

NOS
JAN-Philips 6V6GT Matched Pair
•
$77.95
We get all sorts of questions about what NOS tubes
will work in these amps. To be honest, the answer is way more
complex and highly subjective and conditional. You can head down
a worm hole, losing ducats and sanity and come out other side with empty
pockets and depression. The Law of Diminishing Returns can weigh
heavy. That being said, there is some magic that can be had, especially
with the Single-Ended amps. I use all NOS in my 5w SE Swarts and
a smattering in my PP Swart. The JAN-Philips is not one of my
favorites ala RCA, but it's built like a beast, lasts a while, has ok
tone, and is easier to get. That's something. ~ kh

TAD
6L6WGC-STR Short Bottle Matched Pair
•
$49.95
Hey, this just might be my favorite new 6L6.
Wait, it IS my favorite new 6L6, mainly because it keeps the soul of
the 6V6 alive while adding a bit more headroom and output. I like
this tube in anything from the Atomic Jr to the AST circuits.
This beast avoids some of the slightly sterile nature of the 6L6 retaining
the 6V6's more organic angst and breakup.
More often then not, Michael runs a pair of these in his AST Head Mk
II when playing with the freaks on band nights. I'm running one right
now in my Atomic Jr for a different take. Give it a whirl.
You might be smitten. ~ kh

JJ
GZ-34/5AR4 • $15.95
This is the stock GZ-34/5AR4 rectifier we have used
in every Swart Amplifier besides the first year run of NOS 5Y3 that
finally ran out, much to our chagrin. This has been a pretty robust
tube for the most part, despite suffering a few ups and downs in quality
control. Right now, it's probably the best new GZ-34 out there.
It's still stock in every Swart amp that leaves the shop. If looking
for the most headroom and output, the GZ-34 is the option. We
DO still love the 5Y3 for the extra sweetness and addictive compression.

JJ
5Y3S • $15.95
It's no secret that I dig the NOS 5Y3 rectifier in
some of our circuits, depending on mood and need. I probably run
a NOS 5Y3 in my AST 80% of the time at home. I like the sweeter
tone and more compressed breakup. There is more sag evident.
If not needing the most headroom from the circuit, it's a great option
and puts out 34v less on the tubes, a good thing for longevity.
But there has not been a proper NEW 5Y3 till now. Introducing
the JJ 5Y3S. It's the first of the 5Y3 that actually measures
as a true 5Y3. Long term durability is still unknown but we can
recommend this one based on their work with the GZ-34. I'll do
a follow-up when I get some time with it. There are sites still around
that carry the NOS 5Y3, starting in the mid 20s and going up. ~ kh
