NOS, Soviet military tubes.
Similar
tubes: 7868, 6П41С
Important notice
Although the
6p41s tube is an analogue of the 7868 tube, it
cannot be directly replaced by it, since they have different filament
currents.
Please read
the information on the relevant forums regarding replacement 7868 for 6p41s
before purchasing.
Description:
We have the opportunity to choose a pair
that is very close in characteristics, because As have
more than 800 pcs this tubes (from the same batch).
We have double tested out sets, On our professional
tube tester L3-3. In the output stage of a specially prepared NOVIK amplifier
with real tube operating modes.
All 6P41S tubes from one batch 10'90 made
in the USSR at the Novosibirsk factory!
The tube has a very long resource if it
used correctly. For the possible use of this type of tube in a standard base
from 6L6 or el34
Novik offers a quality converter for those tubes. Weight not more than 36 g. The

Testing process:
All tubes sold by us are tested on a
high-quality Soviet device L3-3. In our laboratory there are three L3-3 of the
latest modifications and several ancient L1-3, each of which has its own
modifications to make the selection of tubes as accurate and high-quality as
possible.
If applicable, we also test the tubes for
noiselessness on a special amplifier bench assembled for such tests.
When selecting tubes, we try to choose
tubes that are as similar as possible in terms of their parameters. The matched
pairs\quads shown in the photo are one such example. The meanings themselves
vary from pair to pair. If you want to have a pair with certain values or know
them before buying - please write to us.
Our standards:
1.
All tubes
we sell have never been used and have been stored in warehouses. We carry out a
careful selection and testing of all tubes on a variety of parameters.
2.
We package
all items securely to prevent any damage during transit.
3.
If you have
special requests for tubes, we are always open to dialogue.

Support:
We are always
ready to help you choose the right tube, saver, converter or socket. If you do
not understand something - you can always write to us, we will help and advise
you.
We have over
40 years of experience with tube amps, during which time we have encountered
the most unusual problems and are always ready to share our experience.
About us:
Qualitatively
tested and selected tubes at a reasonable price! Savers, adapters and
converters for customers who decide to play pipe rolling or extend the life of
their tube amp!
We are
constantly in touch and try to help everyone who decides to join the world of
hot tubes! The main thing is that it is beautiful and cool!
We are
grateful to our colleagues from China, who, with their prices that are
impossible for a Western manufacturer (American or European), made tube
amplifiers affordable for a non-rich client! (Expanded the market at times)
We are
rediscovering for ourselves some types of tubes, which (it turns out) can be
very different in sound from the year of manufacture, batch, plant, country!
Constant monitoring of the forums will help us, as well as many years of
experience in testing tubes and making professional tube amplifiers!
Practically,
all NOS tubes (our subjective opinion) have never been made for HIFI. Especially
Soviet ones! That is why you have to look and try! Less hearing from others,
more listening to yourself - We are all different!
Considering
that many types had a military purpose and are therefore very reliable! The
entire modern remake is an order of magnitude worse in this parameter.
Special orders:
If you did not find the adapter or saver
you need in our store. You can request a custom production. We can produce an
adapter or a saver according to your request, taking into account your wishes
for materials and components.
Return policy:
We are always ready to return the money if
the tubes arrived damaged or did not match the description. We do not accept
returns on the subjective basis of sonic qualities. If you are looking to tube
roll on our dime, look elsewhere. All of our products are guaranteed unless
otherwise stated.� All items all
