Why don't you just ship them from USA? I live in Australia and I'm looking to USA for valves...

Well, there's been mention that the market has been depleted of 19J6 valves. There's a few on eBay but they cost a fortune and it can't be garaunteed that they are matched; they aren't sold in pairs. Many users here have had much success building a variation with 12AU7 valves and their variants...
