The 6H30 is a miniature dual triode that is all the rage today. It comes from Russia and people love it. It is similar to the 6DJ8, but differs in that it is much more buffed: it has a lower rp and mu , plus a greater plate dissipation. However, it requires much more heater current than the 6DJ8. It can be used in a phase splitter and driver circuits in power amplifiers.
