Recently, the DIY tubey movement in Vietnam become stronger than ever, with the advantage with huge stock/tube military source available since Vietnam war.

Last September, the 2nd festival for Viet tubey have been held at Hochiminh city with more than 200 visiteors as well as 15 big amplifiers from whole country. Fyi, because the requirement for participation is DIY amplifier stronger than 15W, therefore we funny named the festival is "Sumo contest"
