In the 90s China bought the whole Mullard factory and shipped it over from England.

If you buy cheap Chinese valves, you're buying Mullard ones which seem to be made to a higher standard than they ever managed in the 80s. Any two random EL34s out of the box will be a closer match than the crazy expensive "super matched pairs" that we used to buy.

Do you have some more info on this? Background, do they still exist? Where is the factory? I visited one older tube factory in China but it was converted to an art/consumption district.
