This is the only products in the world that perfectly reproduce the
Western Electric 212 by far!
WE212 has"there of the most" of audio tubes:most difficult in
production;most perfect in comprehensive sound effects;most
expensive in price.These make PSVANE win the undisputed crown in
the world's history of Audio tubes.And the low price achieved the
ultimate dream of the global enthusiasts.
