About Sophia Electric 6SN7 tubes
Electric 6SN7 tube does not look like a typical 6SN7. By looking at
the internal plate structure, it is more of a European tube structure
rather than North American 6SN7. However the vintage European
ECC32/33, CV181/CV1988 family of tubes are not real 6SN7 tubes. What
is the story? Sophia Electric designers were smart enough to take
European virtue combined with North American 6SN7 electrical tube
characters, further Added with 1920's brass base accent. This is how
these ST shape Sophia Electric 6SN7 tubes were born!
Note: Vintage European CV181/CV1988 historically has been priced in the $150-$200 per tube range, even for used one.
With vintage European CV181/CV1988/ECC33 Gene, Sophia Electric surely would beat any 6SN7 tubes sonically!
Electric 6SN7 would sound with a lot of more openness, more clarity
and less distortion than the very best from vintage time. It just
sounds bigger(better high frequency extension), louder (more drive
voltage swing output), more 3-D imaging for sure (due to better testing
and matching procedure applied in any tube amplifier and
pre-amplifier). Hundreds of users reported Sophia Electric 6SN7 tubes
are better than the vintage 6SN7 tubes being replaced, even the best
from vintage time.
all dual triode tube, has two sections. To match two sections closely
enough is hard enough; match two tubes (four sections would be much
harder if high standard of matching method is applied). Note: a lot
of internet vendors would only test one section of the tube due to the
limitation of their vintage tube tester (like popular TV-7). So those
claimed matched may be matched by one section (with assumption that the
two sections would be identical). However, that assumption was false
Smart buyer would buy Sophia Electric 6SN7 tubes with the
best grade you can afford. It will provide for years of enjoyment.
Why settle for less? The hidden truth behind cheap price is what you
