RE: No Russian or Chinese equiv of the 7189A

Per the link you supplied:

"the 7189 is designed for circuits operating in the 400 volt range. The EL84/6BQ5 is designed for the 300 volt range."

My tube manuals confirm this. But I see LOTS of currently produced guitar amps that use EL84/6BQ5 and run them at 400 volts. In my experience, they seldom arc over internally, but they become microphonic prematurely.
